JavaScript regex returns -1 when > 0 is expected -

-

okay have following string:

aktiv landbruger / regler al

with string attempt run following regex:

/regler al/i

however once run string.search('/regler al/i')

it returns -1

however when attempt on

https://regex101.com/

it returns 0 should.

so why javascript returning -1

remove single quotes around regex

"aktiv landbruger / regler al".search(/regler al/i)
