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"]
|
|
```
