Question

What ECMAScript 6 features can I currently use in web browsers?

Answer 1

The introduction of the ES6 specification lists all new features: Some of [ECMAScript 6's] major enhancements include modules, class declarations, lexical block scoping, iterators and generators, promises for asynchronous programming, destructuring patterns, and proper tail calls.

Answer 2

Answer:

The full form of ECMA is European Computer Manufacturer's Association. ECMAScript is a Standard for scripting languages such as JavaScript, JScript, etc. It is a trademark scripting language specification. JavaScript is a language based on ECMAScript. A standard for scripting languages like JavaScript, JScript is ECMAScript. JavaScript is considered as one of the most popular implementations of ECMAScript.

ECMAScript 6 is working fine on web browsers like Chrome, Microsoft Edge, Safari, etc:

90% compatibility – Chrome

80% compatibility - Microsoft Edge

54% compatibility – Safari

Use ES6 using Babale pre-processor, which cross-compile JavaScript back to ECMAScript 5 compatible code.

Here are features of ECMAScript 6:

Arrow Functions

Declare a function with `=>` instead of to follow ES6 Arrow Functions. This avoids using the usual function expression.

ES6 Modules

ES6 provides modules as part of native JavaScript in the web browser. Modules clean up the code in easy to sustain chunks. This eventually helps in easing code maintenance.

Classes

JavaScript now has support for Classes with an ES6 release. ES6 has brought for OOP, like Inheritance, Constructors, etc.
