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.`.

### escapeRegExp
|
|
|
|
Escapes a string to use in a regular expression.
|
|
|
|
Use `String.prototype.replace()` to escape special characters.
|
|
|
|
```js
|
|
const escapeRegExp = str => str.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');
|
|
```
|
|
|
|
```js
|
|
escapeRegExp('(test)'); // \\(test\\)
|
|
```
