// Don't Do this
let input = document.getElementById('input');
// Checks to see if input is valid.
if (input.value != ''){
    callFunction();
}
    
// Do this instead
let input = document.getElementById('input');
let isValidInput = input.value != '';
if (isValidInput){
    callFunction();
}

// By being verbose with code, you don't need as many comments.
// Why is this good?
// Because you are less likely to reimplement `isValidInput` if you need it in the future.
// It keeps your code DRY: https://en.wikipedia.org/wiki/Don%27t_repeat_yourself
