So, in P5JS, i am trying to create a project, where I input 2 numbers and they are either randomly added, subtracted, multiplied or divided after clicking a button, could someone please show how I would write in JavaScript the code for randomly picking the 4 basic math operations and then the two numbers I inputed are either added, subtracted, multiplied or divided at random once clicking a button?

You can put a random specifier easily:
const randomOpt = Math.floor(Math.random() * 4)
Then, check the randomOpt with a switch and do what you want:
switch(randomOpt) {
case 0:
return inputValue1 + inputValue2
case 1:
// -
case 2:
// *
case 3:
// /
}
It's quite simple
const operations = {
'0': (num1, num2) => num1 + num2,
'1': (num1, num2) => num1 - num2,
'2': (num1, num2) => num1 * num2,
'3': (num1, num2) => num1 / num2,
}
function randomOperation(num1, num2) {
return operations[Math.floor(Math.random() * 4)](num1, num2);
}
