All ECMAScript 2015 (ES6) features are split into three groups for shipping, staged, and in progress features: All shipping features, which V8 considers stable, are turned on by default on Node.js and do NOT require any kind of runtime flag As ES5 is prior to ES6, there is a non-presence of some features, so it has a lower performance than ES6. Because of new features and the shorthand storage implementation ES6 has a higher performance than ES5. Support: A wide range of communities supports it. It also has a lot of community support, but it is lesser than ES5. Object Manipulatio
Though ES6 specification is not super-fresh, I think that many developers are still not so familiar with it. The main reason is probably poor support in web browsers just after specification release. Currently, the specification is over 2 years old, and a lot of modern web browsers work well with ES6 ECMAScript 2015 (ES6) Artboard 1. - OTHER. Support for the ECMAScript 2015 specification.

ES6 is also known as ECMAScript 2015 as it is released in 2015. Its class allows the developers to instantiate an object using the new operator, using an arrow function, in case it doesn't need to use function keyword to define the function, also return keyword can be avoided to fetch the computer value. Difference between ES5 and ES6 As of now, most of the browsers don't fully support the ES6 features. So transpilers like Babel are used which can convert the ES6 code to ES5. Note: ES6 = ECMAScript6 = ECMAScript 2015 = ES2015. ES5 = ECMAScript 2009. ES6 (2015): ES6 was the first and significant update to the language since EcmaScript 2015 which was standardized in 2015 The source is the file features.txt, everything else on es6-features.org is just generated out of it.

Axel's blog 2ality is also a great ES6 resource For each of the ES6 features in question, a ES5 implementation of that functionality was written along with a ES6 version. It should be noted that the functionality is frequently the same, but in some cases the common vs. correct version was written, i.e. using x[key] = value vs. defineProperty which is faster but can be hit but a.
