Top Velocity.js Alternatives and Overview

Velocity.js is a JavaScript animation engine that runs the same API as jQuery's $.animate(). The software can run with and without jQuery. Velocity blends the best of CSS transitions and jQuery. The engine is high-speed and features a multitude of functions, including SVG support, easing, scrolling, loops, transformation, animation, and colour. The steps to experience the performance shift are easy - users have to download Velocity and replace earlier engines with the $.velocity(), to realize an immediate performance uplift.

High Compatibility

Velocity is compatible on nearly all platforms, right from Android 2.3 and IE8. Since the software imitates jQuery's $.queue() under the hood, it operates in a seamless manner with jQuery's $.delay() and $.animate(). Moreover, since the syntax is similar to $.animate(), the user need not change the code. Moreover, the website provides documentation guides and tutorials for users to minimize any complexity in the set--up pr working process.

The Secret to Breakneck Speed

The software falsely bundles jQuery and JavaScript together. Although the JavaScript version that Velocity employs is fast, jQuery remains slow. To address the issue of speed, despite working in tandem with jQuery, Velocity utilizes its animation stack to deliver a high and uncompromised performance. Velocity achieves this by following two fundamental principles—cache values to reduce DOM querying and synchronization of DOM → tween stack to lower layout thrashing.

Performance Optimization

Velocity.js causes dramatic improvements in workflow and UI performance across all devices and browsers. Despite the enormous opportunity potential of the engine, it stayed mostly untapped due to the shortage of web performance understanding among developers. Velocity.js addresses the current issues of speed, compatibility, bugs, and licensing fee for closed-source platforms. The software bears no micro-optimizations, and yet remains incredibly fast due to DOM manipulation and timer creation. Besides, Velocity.js uses a vacuum approach for unit conversion ratios to further lower DOM querying.
