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)); ``` ## Tests Simply clone the repo, `npm install`, and run `npm test` ## Security Please email [@ljharb](https://github.com/ljharb) or see https://tidelift.com/security if you have a potential security vulnerability to report.
