How to convert Number to Hexadecimal String in Javascript


Converting numbers is straightforward similar to that of converting Hex to Number

Here is how to do it

const input = 127;

const hexNumber = input.toString(16) // '7f'

const parsedNumber = parseInt(hexNumber, 16) // 127

// Note: Directly using toString in a number like 127.toString() throws an error.
// Instead, wrap it in a bracket instead.

Basically, when we convert a number to a string using toString we are passing 16 to use hexadecimal notation

Happy playing-with hex!
