+## `path.matchesGlob(path, pattern)`

+
+* `path` {string} The path to glob-match against.
+* `pattern` {string} The glob to check the path against.
+* Returns: {boolean} Whether or not the `path` matched the `pattern`.
+
+The `path.matchesGlob()` method determines if `path` matches the `pattern`.
+
+For example:
+
+```js
+path.matchesGlob('/foo/bar', '/foo/*'); // true
+path.matchesGlob('/foo/bar*', 'foo/bird'); // false
+```
+
+A [`TypeError`][] is thrown if `path` or `pattern` are not strings.
