Compacts whitespaces in a string.
|
|
|
|
- Use `String.prototype.replace()` with a regular expression to replace all occurrences of 2 or more whitespace characters with a single space.
|
|
|
|
```js
|
|
const compactWhitespace = str => str.replace(/\s{2,}/g, ' ');
|
|
```
|
|
|
|
```js
|
|
compactWhitespace('Lorem Ipsum'); // 'Lorem Ipsum'
|
|
compactWhitespace('Lorem \n Ipsum'); // 'Lorem Ipsum'
|
|
```
