JavaScript: How to clear most significant bit?

Question

I'm currently working on a coding challenge that tasks me with converting an integer to a hex value and clearing the MSB. I can use (####).toString(16) to get the integer into a hex but I'm not sure how to clear the MSB.

How many bits do your integers have (i.e. which one is the MSB)? — Bergi, Dec 09 '17 at 19:21
No, you should *not* get your number into a string. Just use bitwise operators. — Bergi, Dec 09 '17 at 19:22

To unset the MSB in a 16 unsigned integer, just use

value &= 0x7FFF;
