    ECMAScript spec abstract operations.

    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 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

    var ES = require('es-abstract');
    var assert = require('assert');
    
    assert(ES.isCallable(function () {}));
    assert(!ES.isCallable(/a/g));
