ECMA Script 6

ES6 Tutorials. Latest Version of Javascript. Supports Modules, spread operators, map, arrays, object literals, template strings, rest operator. ECMAScript 6, also known as ECMAScript 2015, is the latest version of the ECMAScript standard. ES6is a significant update to the language.  ES6 introduces language support for classes (class keyword). ECMAScript defines a collection of built-in objects that round out the definition of ECMAScript entities.  Support for constants (also known as “immutable variables”), i.e., variables which cannot be re-assigned new content. Notice: this only makes the variable itself immutable, not its assigned content (for instance, in case the content is an object, this means the object itself can still be altered).
