In plain English

Rome is a unified toolchain for JavaScript and TypeScript development. Rather than using separate tools for formatting code (like Prettier) and checking it for problems (like ESLint), Rome combines both into a single fast tool. The goal is to reduce the complexity of a JavaScript project's setup by replacing multiple tools with one. The formatter makes code look consistent across a codebase, standardizing indentation, spacing, and style, without developers needing to argue over style rules. The linter checks code for potential bugs and bad patterns. Having both in one tool means faster performance and simpler configuration, since you only need to set things up once. You would use Rome on a JavaScript or TypeScript project where you want fast, integrated formatting and linting without managing multiple tool configurations. It is written in Rust, which is why it is significantly faster than JavaScript-based alternatives. Note: the Rome project was archived and succeeded by a fork called Biome, which continues active development.
