it means that first x is 0 Then we make a for loop in which we increase the value of x each time by 2 so that it goes like this: 0 2 4 6 8 10 and eventually stop at 20 for (let x = 0; x <= 20; x += 2) { }

You need to understand the three elements of this for-loop. for (<integer start value>; <until integer exit criteria>; <steps to do for each iteration>) { <body> } Until: 20 - clear? Step: 2 - every second (x + 2) value -> even numbers, clear?
