How to use regex with not ^ and capture groups? -

how use not operator ^ capture groups in regex.

how make capture group on urls not contain api.

how thought var notapi = /(^api)/;

regex has negative lookaheads , lookbehinds. spirit is: look, don't move forward.

this negative lookahead:

(?!nomatch)

and negative lookbehind:

(?<!nomatch)

you can incorporate these lookarounds regex this:

var notapi = /^((?!api).)*$/;

take @ this answer - explains how works.
