JS is there a way to fix r"egex.test() only works half the time" [SOLVED]

Question

In this code i'm making, I noticed that the regex.test() only works half the time.
I read multiple threads about it on Stack Overflow (no answer though), and they said that it's because of the /text/g, which I don't have. I have a /text/gi though.
Anyways, If you don't know what i'm talking about, you can experiment with the code:
in the textarea, put "how many" and press "send". After a few seconds, it should say "Working". repeat the process. The second time, it'll say "not working" even though you put the same text in the textarea.

If there's no fix for it, let me know if you know a different way to do what I'm tryin to do.
What I'm tryin to do:
var userQuestionA = "how many" or "how much" or "amount";
var userQuestionB = "who r u" or "who are you" or "who are u";
if (input.value matches any of userQuestionA) {ans = "blabla") // shouldn't be case sensitive
if (input.value matches any of userQuestionB) {ans = "blabla"); // shouldn't be case sensitive

Answer 1

your pq variables which the regex that being tested has g.
g inside gi have a same meaning, global
just remove the g, so gi become just i. then it should be good

Answer 2

g is global flag it check regex in whole string.
i is case insensitive flag for regex pattern.
I have send how many thrice and everytime I get working

Answer 3

@Rei I had the /gi there that way it isn't case sensitive. I thought I had to use /gi for that reason, but I guess I don't. I just need the /i
Thank You for the help.
I just needed someone to point something out like that.
