How do you call a function every second in JavaScript?

Question

I know that it’s something to do with setInterval but I can’t figure it out.

Here’s what I have so far:

function plusOne {
document.getElementById("main").innerHTML = x;
x++
}
let x = 0
setInterval(plusOne,1000)

Answer 1

It's all correct, except you forgot the parenthesis in the function declaration. You just need to use
function plusOne () {
to make it work
