What is lazy loading and how does it help?

Lazy loading is a smart way to speed up your site by only loading images, videos, or scripts ONLY when users need them, like when they scroll down the page. Instead of dumping everything upfront, we load the essentials first, which makes pages open faster and feel snappier. This not only saves bandwidth but also gives people, especially on slower networks, a smoother, quicker experience right from the start.
