Stuck on "Regular Expression in Javascript": "The hexRegEx variable does not hold a regular expression object."

Hello, I'm currently on "Regular Expression in Javascript" and I'm stuck in a challenge task. I believe I got the regular expression correct but it's not accepting my code. Can some one take a look?

I've tried:

const hexRegEx = new RegExp(/^[#][a-z0-9]{6}$/gmi).test(text);

It works in the preview though.

Thanks!

Hey there Timothy Haryadi ! :wave:

You're very close! This is what got to pass for me

const hexRegEx = /^#[a-f0-9]{6}$/i;

It wasn't until I removed the new RegEx() code from the value I saw the error message change as it's just wanting the expression.

A very thorough explanation of this can be found here, I definitely recommend checking that out! :smiley:

That did it! Thanks Travis, it also turns out that I had .test(text) at the end. I was ahead of myself. The test() part was supposed to be on the next step.
