Convert tabs to spaces, where each tab corresponds to `count` spaces.
|
|
|
|
- Use `String.prototype.replace()` with a regular expression and `String.prototype.repeat()` to replace each tab character with `count` spaces.
|
|
|
|
```js
|
|
const expandTabs = (str, count) => str.replace(/\t/g, ' '.repeat(count));
|
|
```
|
|
|
|
```js
|
|
expandTabs('\t\tlorem', 3); // ' lorem'
|
|
```
