ESLint vs. TypeScript vs. Velocity.js vs. mailnest Comparison Chart

ESLint is a static code analysis tool for identifying problematic patterns in JavaScript code. It allows developers to configure rules and define custom ones, addressing both code quality and coding style issues. ESLint supports current ECMAScript standards and experimental syntax from future drafts. It can process code using JSX or TypeScript through appropriate plugins or transpilers. The tool is integrated into most text editors and can be part of continuous integration pipelines, enabling automatic problem detection and correction. ESLint is the #1 JavaScript linter by downloads on npm and is used at companies like Microsoft, Airbnb, Netflix, and Facebook. Preprocess code, use custom parsers and write your own rules that work alongside ESLint's built-in rules. Customize ESLint to work exactly the way you need it for your project. Many problems ESLint finds can be automatically fixed. ESLint fixes are syntax-aware so you won't experience errors.

Velocity is an animation engine with the same API as jQuery's animate. It works with and without jQuery. It's incredibly fast, and it features color animation, transforms, loops, easings, SVG support, and scrolling. It is the best of jQuery and CSS transitions combined. Download Velocity, include it on your page and replace all instances of jQuery's animate with velocity. You will immediately see a performance boost across all browsers and devices, especially on mobile. Velocity works everywhere, back to IE8 and Android 2.3. Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance.
