Split string by arithmetic operators

Question

I have a string "str1+str2-str3*str4".

I want to split it so I get an array

['str1','+','str2','-','str3','*','str4'].

Could someone help provide a solution?

Please don't tag something Angular unless the code actually relates to the framework. — ggorlen, Jun 12 '19 at 00:47

If JS split lets capture groups become elements, then this should work

/([-+*\/])/

if not, I suggest using a regular find all type thing
using this

/([-+*\/]|[^-+*\/]+)/

otherwise, I'll just delete this.
