Why does the script work differently?

Question

JavaScript

All good.
There is one script. I run it on different computers. On one it works as it should, on the second the logic of the script sometimes fails. The code is exactly the same. Browsers are the same. What could be causing this?

Answer 1

If(Math.round(Math.random()) == 0){
console.log("It's working")
} else {
console.log("It isn't working")
}
Look for this)
