| Is this value a JS String object or primitive? This module works cross-realm/iframe, and despite ES6 @@toStringTag. |
| |
| ## Example |
| |
| ```js |
| var isString = require('is-string'); |
| var assert = require('assert'); |
| |
| assert.notOk(isString(undefined)); |
| assert.notOk(isString(null)); |
| assert.notOk(isString(false)); |
| assert.notOk(isString(true)); |
| assert.notOk(isString(function () {})); |
| assert.notOk(isString([])); |
| assert.notOk(isString({})); |
| assert.notOk(isString(/a/g)); |
| assert.notOk(isString(new RegExp('a', 'g'))); |
| assert.notOk(isString(new Date())); |
| assert.notOk(isString(42)); |
| assert.notOk(isString(NaN)); |
| assert.notOk(isString(Infinity)); |
| assert.notOk(isString(new Number(42))); |
| |
| assert.ok(isString('foo')); |
| assert.ok(isString(Object('foo'))); |
| ``` |
| |
