I have a string that looks like this:

const str = "income[1].selected"

I would like to get a 3 separate elements by splitting this string by [, ], and . characters. I have tried to do it by:

field.split(/[[\].]/)

But, that gives me 4 elements:

(4) ['income', '1', '', 'selected']

What kind of regex do I need to avoid empty string element?

You can repeat the character class `[[\].]+` – The fourth bird Mar 14 '23 at 13:18
I would recommend against a regex in this case, you are parsing, not card punching here. – Kris Mar 14 '23 at 13:24
How would you parse it to get what I need? @Kris – Leff Mar 14 '23 at 13:27

I would find or create a (typescript) PropertyPath library (like https://codereview.stackexchange.com/questions/173978/javascript-of-property-path-in-object) – Kris Mar 14 '23 at 14:06
