To take most of MetaES, you'll have to learn how it works, otherwise you can just use tools written by others without even being aware of MetaES.

MetaES is a metacircular interpreter. It means it's written JavaScript.

2. Integrates with your application

No matter what app you're building and when it is run:

in browser,

in nodejs,

in extensions,

in any other environment or custom ECMAScript interpreter,

you can benefit from MetaES. It flattens many of your ad-hoc built abstractions, and allows to exchange data between MetaES script and your app.
