Another advantage that the article doesn’t mention is that using this technique over closure makes it easier to inspect its scope via `this`. #### Example ```js import { Namespace } from '@takram/planck-core' // Human-readable name is optional. 'T' should be displayed in the inspector of // your browser as a property of the instance. const internal = Namespace('T') export default class T { constructor(value) { const scope = internal(this) scope.value = value } get value() { const scope = internal(this) return scope.value } } ``` ### Property and Function Call Aggregation `Aggregate` proxies aggregates the calls to its targets as well as to the functions of the targets. Getting a property from an aggregate returns the properties of the first target. Setting a property propagates it to all the targets, resulting the targets should have the same value. Calling a function property (typically a method of instances) applies to all of them and returns an array of their results. #### Example ```js import { Aggregate } from '@takram/planck-core' const a = { value: 'a', func() { return 'a' } } const b = { value: 'b', func() { return 'b' } } const aggregate = Aggregate.new(a, b) aggregate.value = 'c' console.log(a.value) // 'c' console.log(b.value) // 'c' console.log(aggregate.func()) // ['a', 'b'] ``` ### Environment Detection `Global` distinguishes browsers, workers and node processes by `isBrowser`, `isWorker` and `isNode` respectively, and provides unified way to access the global scopes via `scope`. #### Example ```js import { Global } from '@takram/planck-core' if (Global.isNode) { Global.scope.module = require('module') } else if (Global.isWorker) { Global.scope.module = importScripts('/js/module.js') } // Assume the module is already loaded in browser Global.scope.module() ``` ### Promise-based Semaphore The example below limits simultaneous requests by the function `load` to 10. #### Example ```js import { Semaphore } from '@takram/planck-core' const semaphore = new Semaphore(10) function load(url) { // Unlike Promise, the function passed as the argument of “wait” will not be // executed until the semaphore becomes available. return semaphore.wait((resolve, reject) => { const request = new XMLHttpRequest() request.open('get', url) request.onload = () => { if (request.status !== 200) { reject(request.status) } else { resolve(request.response) } } request.onerror = reject request.send() }) } [/* a bunch of urls */].map(url => load(url)) ``` ## API Reference ### Aggregate # **Aggregate**(_target1_ [, _target2_ [, ...]]) # _aggregate_[**property**] # _aggregate_[**property**] = _value_ # _aggregate_([_arg1_ [, _arg2_ [, ...]]]) ### Array # Array.**min**(_array_, _transform_) # Array.**max**(_array_, _transform_) ### AssertionError # new **AssertionError**([_message_]) ### FilePath # FilePath.**resolve**([_path1_ [, _path2_ [, ...]]]) # FilePath.**normalize**(_path_) # FilePath.**join**([_path1_ [, _path2_ [, ...]]]) # FilePath.**relative**(_from_, _to_) # FilePath.**dirname**(_path_) # FilePath.**basename**(_path_ [, _ext_]) # FilePath.**extname**(_path_) # FilePath.**sep** # FilePath.**delimiter** ### Global # Global.**isBrowser** # Global.**isWorker** # Global.**isNode** # Global.**scope** ### Hash # **Hash**(_object_) ### ImplementationError # new **ImplementationError**([_message_]) ### Math # Math.**lerp**(_start_, _stop_, _amount_) # Math.**constrain**(_x_, _min_, _max_) # Math.**map**(_x_, _min1_, _max1_, _min2_, _max2_) # Math.**wrap**(_x_, _min_, _max_) # Math.**radians**(_degrees_) # Math.**degrees**(_radians_) # Math.**sin**(_angle_) # Math.**cos**(_angle_) # Math.**tan**(_angle_) # Math.**asin**(_x_) # Math.**acos**(_x_) # Math.**atan**(y [, x]) # Math.**pow**(_x_, _y_) # Math.**exp**(_x_) # Math.**log**(_x_) # Math.**exp2**(_x_) # Math.**log2**(_x_) # Math.**sqrt**(_x_) # Math.**inversesqrt**(_x_) # Math.**abs**(_x_) # Math.**sign**(_x_) # Math.**floor**(_x_) # Math.**ceil**(_x_) # Math.**fract**(_x_) # Math.**mod**(_x_, _y_) # Math.**min**(_x_, _y_) # Math.**max**(_x_, _y_) # Math.**clamp**(_x_, _min_, _max_) # Math.**mix**(_x_, _y_, _a_) # Math.**step**(_edge_, _x_) # Math.**smoothstep**(_edge0_, _edge1_, _x_) # Math.**length**(_x_) # Math.**distance**(_x_, _y_) # Math.**dot**(_x_, _y_) # Math.**cross**(_x_, _y_) # Math.**normalize**(_x_) # Math.**faceforward**(_N_, _I_ [, _Nref_]) # Math.**reflect**(_I_, _N_) # Math.**refract**(_I_, _N_, _eta_) ### Namespace # **Namespace**([_name_]) # _namespace_(_object_ [, _init_]) ### Request # Request.**text**(_url_ [, _options_])
