In this tutorial, you will learn how to make a Pokemon GO IV Calculator in JavaScript. Basically, this tool can be used to get the IVs of the Pokemon. It means that now you can easily find out if your Pokemon can be the best.
You can even improve this Pokemon GO IV Calculator by adding features like PvP Team Builder for planning your PvP teams in all leagues. Also, get familiar with PvP Strategy and why lower IVs can be better.
The full source code of the Pokemon GO IV Calculator is given below. You can easily copy/paste or download it on your computer and try it yourself.
