How to cache an image in JavaScript?

To cache an image in JavaScript, we can use the lazysizes library.

For instance, we write

<script src="lazysizes.min.js" async></script>

to add the script tag for the library.

<img data-src="images/flower3.png" class="lazyload" alt="" />

to add an img element with the lazyload class.
