The + primary way of interacting with a promise is through its `then` method, which + registers callbacks to receive either a promise's eventual value or the reason + why the promise cannot be fulfilled. + + Terminology + ----------- + + - `promise` is an object or function with a `then` method whose behavior conforms to this specification. + - `thenable` is an object or function that defines a `then` method. + - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). + - `exception` is a value that is thrown using the throw statement. + - `reason` is a value that indicates why a promise was rejected. + - `settled` the final resting state of a promise, fulfilled or rejected. + + A promise can be in one of three states: pending, fulfilled, or rejected. + + Promises that are fulfilled have a fulfillment value and are in the fulfilled + state. Promises that are rejected have a rejection reason and are in the + rejected state. A fulfillment value is never a thenable. + + Promises can also be said to *resolve* a value. If this value is also a + promise, then the original promise's settled state will match the value's + settled state. So a promise that *resolves* a promise that rejects will + itself reject, and a promise that *resolves* a promise that fulfills will + itself fulfill. + + + Basic Usage: + ------------ + + ```js + let promise = new Promise(function(resolve, reject) { + // on success + resolve(value); + + // on failure + reject(reason); + }); + + promise.then(function(value) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Advanced Usage: + --------------- + + Promises shine when abstracting away asynchronous interactions such as + `XMLHttpRequest`s. + + ```js + function getJSON(url) { + return new Promise(function(resolve, reject){ + let xhr = new XMLHttpRequest(); + + xhr.open('GET', url); + xhr.onreadystatechange = handler; + xhr.responseType = 'json'; + xhr.setRequestHeader('Accept', 'application/json'); + xhr.send(); + + function handler() { + if (this.readyState === this.DONE) { + if (this.status === 200) { + resolve(this.response); + } else { + reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); + } + } + }; + }); + } + + getJSON('/posts.json').then(function(json) { + // on fulfillment + }, function(reason) { + // on rejection + }); + ``` + + Unlike callbacks, promises are great composable primitives. + + ```js + Promise.all([ + getJSON('/posts'), + getJSON('/comments') + ]).then(function(values){ + values[0] // => postsJSON + values[1] // => commentsJSON + + return values; + }); + ``` + + @class Promise + @param {Function} resolver + Useful for tooling. + @constructor +*/ + + var Promise$1 = (function() { + function Promise(resolver) { + this[PROMISE_ID] = nextId(); + this._result = this._state = undefined; + this._subscribers = []; + + if (noop !== resolver) { + typeof resolver !== 'function' && needsResolver(); + this instanceof Promise + ? initializePromise(this, resolver) + : needsNew(); + } + } + + /** + The primary way of interacting with a promise is through its `then` method, + which registers callbacks to receive either a promise's eventual value or the + reason why the promise cannot be fulfilled. + ```js + findUser().then(function(user){ + // user is available + }, function(reason){ + // user is unavailable, and you are given the reason why + }); + ``` + Chaining + -------- + The return value of `then` is itself a promise. This second, 'downstream' + promise is resolved with the return value of the first promise's fulfillment + or rejection handler, or rejected if the handler throws an exception. + ```js + findUser().then(function (user) { + return user.name; + }, function (reason) { + return 'default name'; + }).then(function (userName) { + // If `findUser` fulfilled, `userName` will be the user's name, otherwise it + // will be `'default name'` + }); + findUser().then(function (user) { + throw new Error('Found user, but still unhappy'); + }, function (reason) { + throw new Error('`findUser` rejected and we're unhappy'); + }).then(function (value) { + // never reached + }, function (reason) { + // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. + // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. + }); + ``` + If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. + ```js + findUser().then(function (user) { + throw new PedagogicalException('Upstream error'); + }).then(function (value) { + // never reached + }).then(function (value) { + // never reached + }, function (reason) { + // The `PedgagocialException` is propagated all the way down to here + }); + ``` + Assimilation + ------------ + Sometimes the value you want to propagate to a downstream promise can only be + retrieved asynchronously. This can be achieved by returning a promise in the + fulfillment or rejection handler. The downstream promise will then be pending + until the returned promise is settled. This is called *assimilation*. + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // The user's comments are now available + }); + ``` + If the assimliated promise rejects, then the downstream promise will also reject. + ```js + findUser().then(function (user) { + return findCommentsByAuthor(user); + }).then(function (comments) { + // If `findCommentsByAuthor` fulfills, we'll have the value here + }, function (reason) { + // If `findCommentsByAuthor` rejects, we'll have the reason here + }); + ``` + Simple Example + -------------- + Synchronous Example + ```javascript + let result; + try { + result = findResult(); + // success + } catch(reason) { + // failure + } + ``` + Errback Example + ```js + findResult(function(result, err){ + if (err) { + // failure + } else { + // success + } + }); + ``` + Promise Example; + ```javascript + findResult().then(function(result){ + // success + }, function(reason){ + // failure + }); + ``` + Advanced Example + -------------- + Synchronous Example + ```javascript + let author, books; + try { + author = findAuthor(); + books = findBooksByAuthor(author); + // success + } catch(reason) { + // failure + } + ``` + Errback Example + ```js + function foundBooks(books) { + } + function failure(reason) { + } + findAuthor(function(author, err){ + if (err) { + failure(err); + // failure + } else { + try { + findBoooksByAuthor(author, function(books, err) { + if (err) { + failure(err); + } else { + try { + foundBooks(books); + } catch(reason) { + failure(reason); + } + } + }); + } catch(error) { + failure(err); + } + // success + } + }); + ``` + Promise Example; + ```javascript + findAuthor(). + then(findBooksByAuthor). + then(function(books){ + // found books + }).catch(function(reason){ + // something went wrong + }); + ``` + @method then + @param {Function} onFulfilled + @param {Function} onRejected + Useful for tooling. + @return {Promise} + */ + + /** + `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same + as the catch block of a try/catch statement. + ```js + function findAuthor(){ + throw new Error('couldn't find that author'); + } + // synchronous + try { + findAuthor(); + } catch(reason) { + // something went wrong + } + // async with promises + findAuthor().catch(function(reason){ + // something went wrong + }); + ``` + @method catch + @param {Function} onRejection + Useful for tooling. + @return {Promise} + */ + + Promise.prototype.catch = function _catch(onRejection) { + return this.then(null, onRejection); + }; + + /** + `finally` will be invoked regardless of the promise's fate just as native + try/catch/finally behaves + + Synchronous example: + + ```js + findAuthor() { + if (Math.random() > 0.5) { + throw new Error(); + } + return new Author(); + } + + try { + return findAuthor(); // succeed or fail + } catch(error) { + return findOtherAuther(); + } finally { + // always runs + // doesn't affect the return value + } + ``` + + Asynchronous example: + + ```js + findAuthor().catch(function(reason){ + return findOtherAuther(); + }).finally(function(){ + // author was either found, or not + }); + ``` + + @method finally + @param {Function} callback + @return {Promise} + */ + + Promise.prototype.finally = function _finally(callback) { + var promise = this; + var constructor = promise.constructor; + + if (isFunction(callback)) { + return promise.then( + function(value) { + return constructor.resolve(callback()).then(function() { + return value; + }); + }, + function(reason) { + return constructor.resolve(callback()).then(function() { + throw reason; + }); + } + ); + } + + return promise.then(callback, callback); + }; + + return Promise; + })(); + + Promise$1.prototype.then = then; + Promise$1.all = all; + Promise$1.race = race; + Promise$1.resolve = resolve$1; + Promise$1.reject = reject$1; + Promise$1._setScheduler = setScheduler; + Promise$1._setAsap = setAsap; + Promise$1._asap = asap; + + /*global self*/ + function polyfill() { + var local = void 0; + + if (typeof global !== 'undefined') { + local = global; + } else if (typeof self !== 'undefined') { + local = self; + } else { + try { + local = Function('return this')(); + } catch (e) { + throw new Error( + 'polyfill failed because global object is unavailable in this environment' + ); + } + } + + var P = local.Promise; + + if (P) { + var promiseToString = null; + try { + promiseToString = Object.prototype.toString.call(P.resolve()); + } catch (e) { + // silently ignored + } + + if (promiseToString === '[object Promise]' && !P.cast) { + return; + } + } + + local.Promise = Promise$1; + } + + // Strange compat.. + Promise$1.polyfill = polyfill; + Promise$1.Promise = Promise$1; + + return Promise$1; + }); + }.call( + this, + _dereq_('_process'), + typeof global !== 'undefined' + ?

All data is + // referenced by a code, which represents one or more values from the + // original input stream. All input bytes can be referenced as the same + // value as an output code. So if you didn't want any compression, you + // could more or less just output the original bytes as codes (there are + // some details to this, but it is the idea). In order to achieve + // compression, values greater then the input range (codes can be up to + // 12-bit while input only 8-bit) represent a sequence of previously seen + // inputs. The decompressor is able to build the same mapping while + // decoding, so there is always a shared common knowledge between the + // encoding and decoder, which is also important for "timing" aspects like + // how to handle variable bit width code encoding. + // + // One obvious but very important consequence of the table system is there + // is always a unique id (at most 12-bits) to map the runs. 'A' might be + // 4, then 'AA' might be 10, 'AAA' 11, 'AAAA' 12, etc. This relationship + // can be used for an effecient lookup strategy for the code mapping. We + // need to know if a run has been seen before, and be able to map that run + // to the output code. Since we start with known unique ids (input bytes), + // and then from those build more unique ids (table entries), we can + // continue this chain (almost like a linked list) to always have small + // integer values that represent the current byte chains in the encoder. + // This means instead of tracking the input bytes (AAAABCD) to know our + // current state, we can track the table entry for AAAABC (it is guaranteed + // to exist by the nature of the algorithm) and the next character D. + // Therefor the tuple of (table_entry, byte) is guaranteed to also be + // unique. This allows us to create a simple lookup key for mapping input + // sequences to codes (table indices) without having to store or search + // any of the code sequences. So if 'AAAA' has a table entry of 12, the + // tuple of ('AAAA', K) for any input byte K will be unique, and can be our + // key.

Perlin noise is + * a random sequence generator producing a more naturally ordered, harmonic + * succession of numbers compared to the standard random() function. + * It was invented by Ken Perlin in the 1980s and been used since in + * graphical applications to produce procedural textures, natural motion, + * shapes, terrains etc.

        The main difference to the + * random() function is that Perlin noise is defined in an infinite + * n-dimensional space where each pair of coordinates corresponds to a + * fixed semi-random value (fixed only for the lifespan of the program; see + * the noiseSeed() function). p5.js can compute 1D, 2D and 3D noise, + * depending on the number of coordinates given. The resulting value will + * always be between 0.0 and 1.0. The noise value can be animated by moving + * through the noise space as demonstrated in the example above. The 2nd + * and 3rd dimension can also be interpreted as time.

        The actual + * noise is structured similar to an audio signal, in respect to the + * function's use of frequencies. Similar to the concept of harmonics in + * physics, perlin noise is computed over several octaves which are added + * together for the final result.

        Another way to adjust the + * character of the resulting sequence is the scale of the input + * coordinates. As the function works within an infinite space the value of + * the coordinates doesn't matter as such, only the distance between + * successive coordinates does (eg. when using noise() within a + * loop). As a general rule the smaller the difference between coordinates, + * the smoother the resulting noise sequence will be. Steps of 0.005-0.03 + * work best for most applications, but this will differ depending on use. + * + * @method noise + * @param {Number} x x-coordinate in noise space + * @param {Number} [y] y-coordinate in noise space + * @param {Number} [z] z-coordinate in noise space + * @return {Number} Perlin noise value (between 0 and 1) at specified + * coordinates + * @example + *
