A div with an id of 'slideshow' contains five images, the first of which is shown and the others are hidden using a display style of none. Using Javascript, create a simple slideshow that cycles through the images, displaying each image for three seconds at a time, looping back to the first image when the end is reached. You cannot use jQuery or any other library. Instead of asking something easy, with a completely unrealistic caveat that makes it tricky for people who think that the "library" was actually a positive invention, why not ask something not easy. It sounds like you're looking for people who spend their time writing garbage like while(node = node.parentNode){ if(node.className.match(/foo/)) { break; } } because `node.closest('.foo')` isn't hardcore enough. That sounds like a crap engineer to me.
