There's absolute confidence that animations can have a sizeable effect on a website's overall appearance and feel. They're a pleasant feature as long as they may be carried out wisely, and make the user experience nice. Further, you may effortlessly appeal to the eye of your users to push more traffic on your internet site via animations to keep them on your site for a more extended time.

In addition, it's all likelihood that there are numerous JavaScript libraries that we will use to build magnificent animations for our websites thru their use, which permits us to create amazing animations on our webpage.

Let's begin the list of JavaScript animation libraries to try out in no particular order.

1. Anime js

As a Javascript animation library, Anime.js provides a simple yet powerful API that allows work to be done quickly.

It can work with CSS properties, SVG files, DOM attributes, and JavaScript objects. The animations can be played, paused, restarted, reversed, or stopped with the help of Anime.js. Apart from these features, the library also provides a phenomenal number of features for animating elements with follow-throughs and overlaps. Also, we can listen to animation-related events using callbacks and promises, which allow us to get notified whenever we see something that is animated.

One of the key benefits of Anime.js is its flexibility. The library allows users to create a wide range of animations, from simple motion to complex and multi-layered effects. This makes it well-suited for various animation needs, from simple UI animations to more elaborate and interactive effects.

Another advantage of Anime.js is its ease of use. The library has a simple and intuitive API that makes it easy for developers to get started with the library and create their first animations. Even if you're new to web animation, you can quickly and easily create smooth and engaging animations with Anime.js.

An animation library like Anime.js is undoubtedly one of the best on the market. From their website landing page, you can feel the power it offers with the beautiful animations it is built on.

Below are some examples of animation made with anime.js

Morphing: Creates transition between two SVG shapes.

 // anime.js

anime({

    points: [
        { value: '400 150 , 300 250 , 300 400 , 400 500 , 500 400 , 500 250 , 400 150'},
        { value: '400 200 , 400 350 , 300 450 , 400 350 , 500 450 , 400 350 , 400 200'}
    ],
    easing: 'easeOutQuad',
    duration: 2500,
    loop: true
});

Line Drawing: Creates path drawing animation using the 'stroke-dashoffset' property. Set the path "dash-offset" value with anime.setDashoffset() in a from to formatted value.

These are basic examples, but Anime.js offers many more options and features for creating complex and sophisticated animations. You can learn more about using Anime.js by reading the documentation and tutorials on the Anime.js website.

2. Three js

Three.js is a web-based cross-browser JavaScript library and application programming interface which allows the creation of 3D animations for computer graphics in a web browser of any platform by utilizing WebGL and a JavaScript library and application programming interface called Three.js.

The Three.js framework has been designed to make creating 3D computer animations that display in the browser easier, without the need for a standalone application or a plugin, as in traditional cases.

One of the key benefits of Three.js is its versatility. The library allows developers to create a wide range of 3D graphics and animations, from simple geometric shapes to complex and detailed models. This makes it well-suited for a variety of applications, from games and interactive experiences to data visualizations and augmented reality.

Another advantage of Three.js is its performance. Because it is built on top of WebGL, it can use the GPU on users' devices to create high-performance graphics and animations. This means users can experience smooth and responsive graphics and animations, even on devices with limited resources.

Below are some examples of animation made with Three.js

 // three.js 

<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r120/three.min.js"></script>

// create scene
var scene = new THREE.Scene();

// create camera
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );

// create renderer
var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );

// add the renderer to the page
document.body.appendChild( renderer.domElement );

// create cube
var geometry = new THREE.BoxGeometry( 1, 1, 1 );
var material = new THREE.MeshBasicMaterial( { color: 0x808080} );
var cube = new THREE.Mesh( geometry, material );

// add cube to scene
scene.add( cube );

// move  camera back
camera.position.z = 5;

// animate
function animate() {
  requestAnimationFrame( animate );
  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;
  renderer.render( scene, camera );
}
animate();

This is an elementary example, but it shows the basic steps involved in creating a 3D scene with Three.js. You can learn more about using Three.js by reading the documentation and tutorials on the Three.js website.

Overall, Three.js is a powerful and versatile library for creating 3D graphics and animations on the web. Whether you're a web developer looking to create immersive experiences or a designer looking to visualize data in new and engaging ways, Three.js is a great tool to consider.

3. Velocity js

With Velocity.js, We can use the same API as jQuery's $.animate() as an animation engine. It is compatible with both jQuery and without it. It is extremely fast and features a wide range of features, including color animation, transforms, loops, easings, SVG support, and scrolling. It combines jQuery and CSS transitions and has the best of both worlds.

In addition, Velocity also offers good compatibility, particularly with older browser platforms. Aside from having great documentation, Velocity.js also has a great community willing to help you if you require assistance.

Below are some examples of animation made with velocity.js

    });
  }

  loader();

});

5. Mo js

JavaScript motion graphics library Mo.js is fast, retina-ready, modular, and open source. The syntax of this library and how code animations are structured are different from those of other libraries. As a result of the declarative API, the animation is entirely customizable, which makes it easy to create new animations.

There are built-in components in this library to help you start animating from scratches, such as HTML and shape and swirls, bursts, and staggers, but there are also tools to help you craft your animation naturally. Mo.js allows you to create delightful animations with accuracy, enhance the user experience, and enrich your content visually on your site.
