+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')));
+```
+
