Mathias Bynens 8ee50178f3 Avoid confusing prototype methods for static methods
Correct: `Array.from()` (it’s a static method)
Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method)

This patch uses the common `#` syntax to denote `.prototype.`.

### words
Converts a given string into an array of words.
Use `String.prototype.split()` with a supplied pattern (defaults to non-alpha as a regexp) to convert to an array of strings. Use `Array.prototype.filter()` to remove any empty strings.
Omit the second argument to use the default regexp.
```js
const words = (str, pattern = /[^a-zA-Z-]+/) => str.split(pattern).filter(Boolean);
```
```js
words('I love javaScript!!'); // ["I", "love", "javaScript"]
words('python, javaScript & coffee'); // ["python", "javaScript", "coffee"]
```
