Every operation is available by edition/year and by name - for example, `es-abstract/2020/Call` gives you the `Call` operation from ES2020, `es-abstract/5/Type` gives you the `Type` operation from ES5.
All abstract operations are also available under an `es5`/`es2015`/`es2016`/`es2017`/`es2018`/`es2019`/`es2020`/`es2021` entry point, and as a property on the `main` export, but using deep imports is highly encouraged for bundle size and performance reasons. Non-deep entry points will be removed in the next semver-major release.
## Example
```js
var ES = require('es-abstract');
var assert = require('assert');
assert(ES.isCallable(function () {}));
assert(!ES.isCallable(/a/g));
```
