es-abstract 
ECMAScript spec abstract operations.
When different versions of the spec conflict, the default export will be the latest version of the abstract operation.
All abstract operations will also be available under an es5/es2015/es2016/es2017/es2018/es2019 entry point, and exported property, if you require a specific version.
Example
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
