function test() {
  let counter = 0;
  var bool = false;
  const i = setInterval(function(){
      console.log(counter);
      counter++;
      if(counter === 5) {
        bool = true;
        clearInterval(i);
      }
  }, 200);
  return bool;
}
if (test() == true) {
  console.log(true);
} else {
  console.log(false);
}

Output

The test function doesn't wait for setInterval to finish, do bool is never set to true by your interval function.

To do what you want to do you'd need to use a promise or have a function that you call when the interval is cancelled.

Here's an example https://stackoverflow.com/a/56469184

Stack Overflow

async await with setInterval

function first(){
console.log('first')
}
function second(){
console.log('second')
}
let interval = async ()=>{
await setInterval(first,2000)
await setInterval(second,2000)
}
interval();

#

You'd need to call resolve when you clear the interval
