The negative lookbehind (?<!) asserts regex_1
not to be immediately preceded by regex_2
. Lookbehind is excluded from the match (do not consume matches of regex_2
), but only assert whether a match is possible or not.
Task
You have a test String .
Write a regex which can match all the occurences of characters which are not immediately preceded by vowels (a, e, i, u, o, A, E, I, O, U).
Note
This is a regex only challenge. You are not required to write a code.
You have to fill the regex pattern in the blank (_________
).
JavaScript do not support lookbehind.
