This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

its because your regex matches entire section [a,b,c] there [s,b,c] instead of just [a,b,c]

Your [.*] pattern matches [a,b,c] there [s,b,c] and thus remove this substring and puts an empty string and the rest of the string into an array. Use a non-greedy (also called "lazy") quantifier, *?, instead of *. You may remove empty matches by adding .filter(Boolean) to the split result. Also, to split with whitespace, too, at the same time, use .split(/[.*?]|s+/).filter(Boolean).

You shouldn't be greedy:

str3.split(/[.*?]s*/);
