Lazy loading is a technique that improves the performance and speed of your WordPress website by only loading the images and videos that are visible to the user. This way, your site doesn’t have to download all the media files at once, which can slow down the loading time and consume more bandwidth.
In this blog post, I will show you how to add lazy load function to WordPress pages using three different methods: upgrading to WordPress 5.4 or higher, enabling native lazy loading through the browser, or installing a plugin.
Method 1: Upgrade to WordPress 5.4 or Higher
The easiest way to add lazy load function to WordPress pages is to upgrade your WordPress version to 5.4 or higher. WordPress 5.4 and newer versions include lazy loading images by default, so you don’t have to do anything else.
However, this method has some drawbacks. First, it doesn’t allow you to configure which images to lazy load, so your website may overuse the feature and cause content buffering or slow scrolling. Second, it doesn’t support lazy loading videos, which can also affect your site speed and performance.
To upgrade your WordPress version, go to Dashboard > Updates and click on Update Now. Make sure you backup your site before updating.
Method 2: Enable Native Lazy Loading Through the Browser
Another way to add lazy load function to WordPress pages is to enable native lazy loading through the browser. This means that the browser will decide when to load the images and videos based on its own criteria, such as the distance from the viewport or the network conditions.
To enable native lazy loading through the browser, you need to add a loading attribute to your image and video tags. The loading attribute supports three values: auto, lazy, and eager.
– Auto: triggers default lazy loading, which is the same as not including a loading attribute.
– Lazy: delays the loading of the assets until they reach a certain distance from the viewport.
– Eager: loads the assets immediately, regardless of their position on the page.
For example, if you want to lazy load an image, you can add loading=”lazy” to its tag:
<img src=”image.jpg” alt=”Image” loading=”lazy”>
You can also use a plugin like Autoptimize or WP Rocket to automatically add the loading attribute to your images and videos.
However, this method also has some limitations. First, it depends on the browser support, which may vary across different devices and platforms. Second, it doesn’t give you much control over how and when to load the assets, which may affect your user experience and SEO.
Method 3: Install a Plugin
The third and most flexible way to add lazy load function to WordPress pages is to install a plugin. There are many plugins that can help you lazy load your images and videos, such as a3 Lazy Load, Lazy Load by WP Rocket, Smush, or Jetpack.
These plugins allow you to customize various aspects of lazy loading, such as:
– Which images and videos to lazy load
– The distance from the viewport for triggering lazy loading
– The placeholder image or animation for lazy loading
– The compatibility with other plugins and features
– The exclusion of certain pages or posts from lazy loading
To install a plugin for lazy loading, go to Plugins > Add New and search for the plugin name. Then click on Install Now and Activate.
For example, if you want to use a3 Lazy Load, you can install it from the WordPress repository and then go to Settings > a3 Lazy Load to configure its options.
Conclusion
Lazy loading is a great way to improve your WordPress site speed and performance by only loading the images and videos that are visible to the user. You can add lazy load function to WordPress pages using three different methods: upgrading to WordPress 5.4 or higher, enabling native lazy loading through the browser, or installing a plugin.
Each method has its own advantages and disadvantages, so you need to choose the one that suits your needs and preferences. You can also test your site speed before and after adding lazy load function using tools like GTmetrix or Pingdom.

Introduction to React JS
/in ReactReact JS is a popular JavaScript library for building user interfaces. It was created by Facebook and is used by many websites and applications. In this blog post, we will learn what React JS is, how it works, and why you should use it.
What is React JS?
React JS is a library that lets you create and manage components, which are reusable pieces of UI that can display data and handle user interactions. Components can be composed together to form complex UIs, such as pages, screens, and apps.
React JS uses a syntax called JSX, which is an extension of JavaScript that allows you to write HTML-like markup inside your JavaScript code. JSX makes it easy to express the structure and style of your UI in a declarative way.
React JS also uses a feature called state, which is a way of storing and updating data in your components. State can change over time, such as when the user types into an input or clicks a button. React JS automatically updates the UI to reflect the new state, without you having to write any code to manipulate the DOM.
Why use React JS?
React JS has many benefits that make it a great choice for building user interfaces. Some of them are:
– It is fast and efficient. React JS uses a virtual DOM, which is a representation of the real DOM in memory. React JS only updates the parts of the DOM that have changed, instead of re-rendering the whole UI every time the state changes. This makes React JS very performant and responsive.
– It is modular and scalable. React JS encourages you to break down your UI into small and independent components that can be reused and tested easily. This makes your code more organized, maintainable, and adaptable to changing requirements.
– It is easy to learn and use. React JS has a simple and intuitive API that lets you create components with just functions and JSX. You don’t need to learn any complex concepts or frameworks to use React JS. You can also use existing JavaScript tools and libraries with React JS, such as webpack, Babel, TypeScript, etc.
– It is fun and creative. React JS gives you the freedom and flexibility to create any kind of UI you can imagine. You can use React JS to build web apps, mobile apps, desktop apps, games, VR experiences, and more.
How to get started with React JS?
To get started with React JS, you need to set up a React environment on your computer. You can use a tool called create-react-app, which is an officially supported way to create React applications. You also need Node.js installed on your computer to use create-react-app.
To create a new React app, open your terminal in the directory you want to create your app in, and run this command:
npx create-react-app my-app
This will create a new folder called my-app with all the files and dependencies you need for your React app.
To run your app in development mode, go inside the my-app folder and run this command:
npm start
This will open your app in your browser at http://localhost:3000.
You can now edit the files in the src folder to create your own components and UIs with React JS.
To learn more about React JS, you can visit the official website at https://reactjs.org/, where you can find documentation, tutorials, examples, and community resources.
Conclusion
React JS is a powerful and popular JavaScript library for building user interfaces. It lets you create components with JSX and state, and updates the UI automatically when the state changes. It is fast, efficient, modular, scalable, easy to learn and use, fun and creative. You can use React JS to build any kind of UI you want for any platform you want.
I hope this blog post gave you a good introduction to React JS and inspired you to try it out yourself. Happy coding!

Introduction to React: Building Powerful User Interfaces
/in ReactReact is an open-source JavaScript library that is used for building user interfaces (UI). Developed by Facebook, it has gained immense popularity since its launch in 2013. It is a fast, efficient, and flexible library that simplifies the process of building complex UIs.
React’s popularity can be attributed to its declarative programming approach, which allows developers to describe how a UI should look and behave. This eliminates the need for manually manipulating the DOM, making the code cleaner, more modular, and easier to maintain.
One of the key features of React is its component-based architecture. Components are independent, reusable blocks of code that can be combined to create more complex UIs. React components can be divided into two types: functional and class components. Functional components are simpler and more lightweight, while class components are more powerful and can have more advanced features like state and lifecycle methods.
React also offers a virtual DOM (Document Object Model), which is a lightweight representation of the actual DOM. This allows React to efficiently update only the parts of the UI that have changed, rather than re-rendering the entire UI. This feature results in improved performance and faster updates to the UI.
React is often used in conjunction with other tools and technologies, such as Redux for state management, React Native for building mobile applications, and webpack for bundling and optimizing the code. React’s flexibility and compatibility with other libraries make it a popular choice for developers of all levels.
In conclusion, React is a powerful and efficient JavaScript library that simplifies the process of building complex user interfaces. Its declarative programming approach, component-based architecture, and virtual DOM make it a popular choice among developers. With the help of React, building dynamic and interactive UIs has become much easier and more efficient.
