There are a couple issues with your code. Mainly, you are passing in actual values instead of parameters. You will pass in the actual values such as 10, and 90 when you call the function. Secondly, you forgot your semicolons after the return statements.

function max(a, b) {
  if (a > b) {
    return a;
  } else {
    return b;
  }
}

alert(max(2, 6))

An alert is like a popup. A message box. A return statement is used to exit a function and "return" a value to use elsewhere.
