What is Lazy Loading?

Most of the time, when the user visits any web page, he doesn't notice how long it takes for images to load. But if it is taking too much time, it will be frustrating. That's where lazy loading comes in to optimize website speed.

Lazy loading is nothing but a method of delaying the loading of resources, such as images, until they are actually required. It's an optimization process for websites that can help reduce initial loading time and improve the user experience.

Let's say you have a blog post with multiple images. Usually, as soon as a reader visits your post, all the images on the page start to load. This can consume a lot of user data and increase your page load time, making the site slower. But, with lazy loading, you can defer (profess of delaying) the offscreen images. This means images will only load after the user scrolls down to the point where the images are located. This technique helps reduce the page weight, saves data, and moreover controls both server and client load resources.

Enabling lazy loading for images has several advantages. It not only reduces the initial load time but also helps improve website speed and user experience. And in addition to that, it saves bandwidth by delivering content to users only if it's requested. So, if you want to optimize your website's speed and improve user experience, lazy loading is a recommended technique to consider.

6. Improved conversion rates: A better user experience and faster page load times can lead to improved conversion rates, as users are more likely to engage with and purchase from a website that performs well.

Page loading VS Lazy loading

• Page loading: When you open any URL, your browser requests the data from the server, downloads all the images, texts, scripts, and it all affects big usage of bandwidth, causes slower page loading performance. Your page loading badly affected and so the bounce rate. So to overcome this, deferring the image loading is the best option to adopt.
  
  
• Lazy loading: It is the mechanism of deferring to load all data from the server until required instead of loading in advance. This can drastically increase web performance by decreasing the load on bandwidth usage that required to be rendered and shown on screen. Lazy loading of images is nothing but to load all image files only shown on the screen as per requests sequentially.
  
  
• Lazyloader script: A lazy loader is a jQuery plugin composed in JavaScript which differs the loading of image files while loading of web pages. Offscreen images outside of the visible part of the page (viewport) will not be downloaded until the user scrolls. If you using several images in your post, then lazy loading will make the page load faster by loading text first followed by images on scroll. Moreover, it also helps to reduce server load.

What Does ASYNC and DEFER Means?

Both async and defer are attributes for the <script> element, used to control the loading and execution of external JavaScript files.

• ASYNC specifies that the script should be downloaded asynchronously, while the HTML page continues to load. Once the script is downloaded, it will execute immediately, potentially before the HTML page has finished rendering. This can speed up the page load time but may cause issues if the script is dependent on elements that havent been loaded yet.
• DEFER specifies that the script should be downloaded asynchronously, but it will only execute after the HTML page has finished parsing. This can help avoid issues with scripts being dependent on unloaded elements but may cause a delay in the script execution.

In summary, async is suitable for scripts that do not depend on the page content,
where as defer is suitable for scripts that do depend on the page content.
