ecmascript-5

I've been trying to understand how this value is set in javascript, and found ECMAScript Language Specification pretty much helpful. I was reading section 8.7 reference specification type and found that reference in ECMAScript is made of 3 component, base value , referenced name , strict reference flag to understand section 11.2.3 . I can assume what are referenced name and strict reference flag from their name, but i don't understand what is the base value . The document says that base value is either undefined , String , Boolean , Number and Object , but it does not say how it is set and

Given that the ES 5.1 standard states that... 1) Note at the foot of http://es5.github.com/#x13.2 NOTE A prototype property is automatically created for every function, to allow for the possibility that the function will be used as a constructor. 2) http://es5.github.com/#x15.3.5.2 NOTE Function objects created using Function.prototype.bind do not have a prototype property. (which implies that all other functions do) ...why do built-in functions no longer have a prototype property?: [].push.prototype; //undefined Math.max.prototype; //undefined Moreover these built-ins cannot be used as

I'm looking for a way to accomplish a certain task and that is, going from jQuery.when.apply( null, promiseArray ).done(...) to when( promiseArray ).done(...) As you might know, .bind() can get used to create something like default arguments and also doing some quite nifty stuff. For instance, instead of always calling var toStr = Object.prototype.toString; // ... toStr.call([]) // [object Array] we can do it like var toStr = Function.prototype.call.bind( Object.prototype.toString ); toStr([]) // [object Array] This is fairly cool (even if there is a performance penality invoking .bind() like

I am trying to run this code but it is giving me following errors: Animal.ts(10,13): error TS1056: Accessors are only available when targeting ECMAScript 5 and higher. Animal.ts(14,13): error TS1056: Accessors are only available when targeting ECMAScript 5 and higher. interface IAnimal{ name : string; sayName():string; } class AnimalImpm implements IAnimal{ private _name : string = '[Animal]'; get name():string{ return this._name; } set name(name:string){ this._name = name; } constructor(name:string){ this.name = name; } sayName():string { console.log(`My name is ${this.name}`); return "Hello"

I want to call an inner function from a static function that was called without an instance, like so: Foo.Bar = function (options) { Autodesk.Viewing.Extension.call(this, options); ... this.innerFunc = function innerFunc(){ ... } }; Foo.Bar.prototype.constructor = Foo.Bar; Foo.Bar.SomeStaticFunc = function () { innerFunc(); } Use: Foo.Bar.SomeStaticFunc(); . But I get SomeStaticFunc is not a function . The example here uses a variable for the class, like var Foo.Bar = function (options) {... but isn't that the same as making an instance of the class like so and calling an inner function? let x
