Step-by-step animation in a for loop - how?

Question

JavaScript

Dear front-end gurus! Tell me, is there an adequate way for step-by-step animation? There is a for
loop in which the value of the i -th cell is changed (on an impromptu field of divs ). How to show visually step by step value change? There is nothing to do here without setTimeout . But how to do it correctly?

Answer 1

You need setInterval , not setTimeout

Answer 2

without setTimeout - measure elapsed time
