I wanted to build Carousel on my own without using any Frameworks as well as other web implementations. This is what I came up with. I made use of Arrays. Initially, I made use of images which were 4 mb for each and caused a lot of delay for images to load. I have lot of optimization in mind. Maybe I can make use of a package such as imagemin to reduce image file size as well as lazy load images. Another thing, I haven't minified the file, guess it can improve the performane.
