Clones a regular expression.
|
|
|
|
- Use the `RegExp` constructor, `RegExp.prototype.source` and `RegExp.prototype.flags` to clone the given regular expression.
|
|
|
|
```js
|
|
const cloneRegExp = regExp => new RegExp(regExp.source, regExp.flags);
|
|
```
|
|
|
|
```js
|
|
const regExp = /lorem ipsum/gi;
|
|
const regExp2 = cloneRegExp(regExp); // regExp !== regExp2
|
|
```
