Tip Calculator App using CSS | Bootstrap | Javascript

Hey, Halibal.

One simple change would be to consolidate your calculatep5, calculatep10, etc. functions into one function, since they all do the same thing. You can define a parameter for the percentage, and then replace the hard-coded number in your function with the variable.

function calculatep(percentage) {
  ...
  let tip = billP / percentage /NoPP
  ...
}

And call the function like so: calculatep(15)

I recently completed this challenge, so you can check out my code if you'd like.
