[ES6] 21. Esnext, Es6-shim & Node

Es-next:

Esnext is similar to traceur, you can use command line to compile files.

Install:

Install esnext-g

Here's how to compile a, a single file, a print it to stdout:

Esnext Myfile.js

To compile many files at once, specify an output directory:

Esnext-o build lib/**/*.js

To enable source maps for these files, add the **--source-maps** flag.

But Esnext doesn ' t support as many ES6 features as traceur, so it's not that popular.

Es-shim

Es-shim is different from traceur and Esnext. It is a list of shim and polyfills which you can include and use in the browser.
So it's really easy-to-use.

Install:

Install Es6-shim

Node

For Windows, need-install nodist for Node Manager.
