The string is:

var string = `1. A<br>2. B<br>3. C`;

Now splitting by regex:

var results = string.split(/\d+\./);

Results in:

(4) ['', ' A<br>', ' B<br>', ' C']

What I actually expected:

(3) [' A<br>', ' B<br>', ' C']

What is the problem here? Is the first result always empty in Javascript when using a split with Regex?
