setting of translateX for carousel image slider

+3
−0

I made carousel image slider by following tutorials.

To slide images , I made the below function.

const moveToSlide = (track, currentSlide, targetSlide) => {
track.style.transform = 'translateX(-' + targetSlide.style.left + ')'; 
currentSlide.classList.remove("current-slide"); 
targetSlide.classList.add("current-slide"); 
 }

I can't figure out how it works when you click "left" button. I think it should be

'translateX(+ ' + targetSlide.style.left + ')';

if you want to slide to left. I think I'm misunderstanding something....

Unless you want to play a game of pinning the tail on the donkey, it is in my opinion it good idea to start troubleshooting/debugging by outputting the composed string 'translateX(+ ' + targetSlide.style.left + ')' to the (browser) console so you can inspect the actual transform string your code is setting. Check whether the translation values in that string are valid (i.e., a number including a unit) and whether the values are what you would expect.

That said, what's up with the + character followed by a space in your transform string? What could this possibly achieve that a transform string without that + char could not? I speculate that the space after the + char is perhaps making for invalid numbers (+1 might perhaps be a valid number, but perhaps + 1 would not be a valid number as far as parsing transform strings is concerned; but i do not really know...)
