Can someone please explain this in word , what this code says actually!

Question

if(num >= images.length) {
num = 0;
}

Answer 1

images is an object that has a length property, probably an array that tells you how many elements it contains and if num becomes greater or equal than the length (in a loop probably) num takes the value 0 (and probably loop starts over or ends)

Answer 2

Thanks Valan

Sorry but still for me this is not clear

its ok if ( num= images.length)

but confuse if(num>images.length)

because here is ( num=0)

why this isnot if(num<=images.length)
