How to set a delay in a for loop?

Question

JavaScript

There is a task: in an array of elements to hide in turn each element.

I select elements through for, but how to set a delay of at least 300ms between each iteration?

Answer 1

var i = 0;
var max_i = 10;
var interval = null;

interval = setInterval(function() {
  // some code
  
  i++;

  if (++i > max_i) {
    clearInterval(interval);
  }
}, 300);
