The [`String#replaceAll()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replaceAll) method is both faster and safer as you don't have to use a regex and remember to escape it if the string is not a literal. And when used with a regex, it makes the intent clearer.

## Examples

```js
// ❌
string.replace(/RegExp with global flag/igu, '');

// ✅
string.replaceAll(/RegExp with global flag/igu, '');
```

```js
// ❌
string.replace(/RegExp without special symbols/g, '');

// ✅
string.replaceAll('RegExp without special symbols', '');
```

```js
// ❌
string.replace(/\(It also checks for escaped regex symbols\)/g, '');

// ✅
string.replaceAll('(It also checks for escaped regex symbols)', '');
```

```js
// ❌
string.replace(/Works for u flag too/gu, '');

// ✅
string.replaceAll('Works for u flag too', '');
```

```js
// ❌
string.replaceAll(/foo/g, 'bar');

// ✅
string.replaceAll('foo', 'bar');
```

```js
// ✅
string.replace(/Non-global regexp/iu, '');
```

```js
// ✅
string.replace('Not a regex expression', '')
```

```js
// ✅
string.replaceAll(/\s/g, '');
```
