Returns a string with whitespaces removed.
|
|
|
|
- Use `String.prototype.replace()` with a regular expression to replace all occurrences of whitespace characters with an empty string.
|
|
|
|
```js
|
|
const removeWhitespace = str => str.replace(/\s+/g, '');
|
|
```
|
|
|
|
```js
|
|
removeWhitespace('Lorem ipsum.\n Dolor sit amet. ');
|
|
// 'Loremipsum.Dolorsitamet.'
|
|
```
