Works with Functions and GeneratorFunctions, despite ES6 @@toStringTag. ## Example ```js var isCallable = require('is-callable'); var assert = require('assert'); assert.notOk(isCallable(undefined)); assert.notOk(isCallable(null)); assert.notOk(isCallable(false)); assert.notOk(isCallable(true)); assert.notOk(isCallable([])); assert.notOk(isCallable({})); assert.notOk(isCallable(/a/g)); assert.notOk(isCallable(new RegExp('a', 'g'))); assert.notOk(isCallable(new Date())); assert.notOk(isCallable(42)); assert.notOk(isCallable(NaN)); assert.notOk(isCallable(Infinity)); assert.notOk(isCallable(new Number(42))); assert.notOk(isCallable('foo')); assert.notOk(isCallable(Object('foo'))); assert.ok(isCallable(function () {})); assert.ok(isCallable(function* () {})); assert.ok(isCallable(x => x * x)); ``` ## Tests Simply clone the repo, `npm install`, and run `npm test` [1]: https://npmjs.org/package/is-callable [2]: http://versionbadg.es/ljharb/is-callable.svg [3]: https://travis-ci.org/ljharb/is-callable.svg [4]: https://travis-ci.org/ljharb/is-callable [5]: https://david-dm.org/ljharb/is-callable.svg [6]: https://david-dm.org/ljharb/is-callable [7]: https://david-dm.org/ljharb/is-callable/dev-status.svg [8]: https://david-dm.org/ljharb/is-callable#info=devDependencies [9]: https://ci.testling.com/ljharb/is-callable.png [10]: https://ci.testling.com/ljharb/is-callable [11]: https://nodei.co/npm/is-callable.png?downloads=true&stars=true [license-image]: http://img.shields.io/npm/l/is-callable.svg [license-url]: LICENSE [downloads-image]: http://img.shields.io/npm/dm/is-callable.svg [downloads-url]: http://npm-stat.com/charts.html?package=is-callable
