ESLint vs. JavaScript vs. ReSharper vs. Roy 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.
