es-to-primitive

ECMAScript ?ToPrimitive? algorithm. Provides ES5 and ES6 versions. When different versions of the spec conflict, the default export will be the latest version of the abstract operation. Alternative versions will also be available under an es5/es6/es7 exported property if you require a specific version.

Example

toPrimitive = require('es-to-primitive');
assert = require('assert');

rt(toPrimitive(function () {}) === String(function () {}));

date = new Date();
rt(toPrimitive(date) === String(date));

rt(toPrimitive({ valueOf: function () { return 3; } }) === 3);

rt(toPrimitive(['a', 'b', 3]) === String(['a', 'b', 3]));

sym = Symbol();
rt(toPrimitive(Object(sym)) === sym);
