Converting Binary To Hexadecimal

I am converting binary to hexadecimal but the code below returns a wrong answer: var number = 1011; var hexa = parseInt(number, 2).toString(16); return hexa; This returns b but it

Solution 1:

'b' is correct. Hexadecimal doesn't specify letter case, and many write hex strings with lower-case letters.

Solution 2:

Just add toUpperCase():

var hexa = parseInt(number, 2).toString(16).toUpperCase();
