This is a great question. Thanks for sharing. Even I got confused a little 😃 https://javascript.info/regexp-greedy-and-lazy But going through this awesome article the purpose of '?' as lazy quantifier became crystal clear 👌 This article explains very clearly how the use '?' after other identifiers like '* 'or in your case '+' makes it lazy and hence able to find multiple matches. I am off to my favorite regex playground to play with this myself. https://regex101.com/

Bartas Dausynas yes when I done solving algorithm problem with many If else, loops and many lines of code and then see other solutions they solve the same problem with just one line of regex.
