Indents each line in the provided string.
|
|
|
|
- Use `String.prototype.replace()` and a regular expression to add the character specified by `indent` `count` times at the start of each line.
|
|
- Omit the third parameter, `indent`, to use a default indentation character of `' '`.
|
|
|
|
```js
|
|
const indentString = (str, count, indent = ' ') => str.replace(/^/gm, indent.repeat(count));
|
|
```
|
|
|
|
```js
|
|
indentString('Lorem\nIpsum', 2); // ' Lorem\n Ipsum'
|
|
indentString('Lorem\nIpsum', 2, '_'); // '__Lorem\n__Ipsum'
|
|
```
