Sometimes, we want to convert integers to hex string in JavaScript.
In this article, we’ll look at how to convert integers to hex string in JavaScript.
How to convert integers to hex string in JavaScript?
To convert integers to hex string in JavaScript, we can use the number’s toString method.
For instance, we write:
const g = 255;
const gPadded = Number(g).toString(16).padStart(2, "0");
console.log(gPadded)
to convert g to a number with Number.
Then we call toString with 16 to convert the number to a hex string.
Finally, we call padStart with length 2 and string '0' to pad the string to 2 characters with 0’s at the start of the string.
So gPadded is 'ff'.
Conclusion
To convert integers to hex string in JavaScript, we can use the number’s toString method.
