Cloning a Regular Expression

To clone a regular expression, use the RegExp constructor, RegExp.prototype.source, and RegExp.prototype.flags.

const cloneRegExp = (regExp) => new RegExp(regExp.source, regExp.flags);

This code will create a clone of the given regular expression. For example:

const regExp = /lorem ipsum/gi;
const regExp2 = cloneRegExp(regExp); // regExp !== regExp2
