Why is ES6 better than JavaScript?

Reason 2: ES6 is really fast. In the process, they extracted their JavaScript runtime from the web browser into something called NodeJS (which is the JavaScript programming language minus a web browser). And since ES6 can be rewritten to be run in an ES5, ES6 benefits from all of JavaScript’s performance optimizations.

Do any browsers not support ES6?

Using ES6 is not possible unless we limit ourselves to the few browsers that already support it. Microsoft Edge, Firefox, Chrome and iOS Safari all have a good sub-set of ES6 implemented. However, not all these browsers are what our users have, and we can not assume people upgrade all the time.

What’s the best way to write JavaScript in ES6?

If you want to use most of ES6 capabilities today in a wide range of browsers, then your best option is probably to transpile your code using something like BabelJS. This will transpile your ES6 code into ES5 compatible code that will run in any ES5 browser. You get to write in ES6, but the code will run in a wide range of browsers.

Is the ES6 JS engine backward compatible with JavaScript?

Many ES6 features are not backward compatible and will only work in an ES6 JS engine. If your code runs in a browser, it will either only work in the newest browsers or you will have to wait until your entire browser support base is up to ES6 (years from now).

Why is ES6 not compatible with older browsers?

New ES6 features that represent new language syntax are simply not that way as older browsers don’t know how to process them and even if they could somehow ignore the newer syntax, they don’t support the functionality that the new syntax implies.
