JS regex split can return also matched results

In Javascript by using:

"One <a> Two <b> Three".split(/<[a-z]>/g)

We will get in result:

(3) ["One ", " Two ", " Three"]

By adding parentheses to this regex we can receive also matched results:

"One <a> Two <b> Three".split(/(<[a-z]>)/g)

Result:

(5) ["One ", "<a>", " Two ", "<b>", " Three"]
