RSLint is an extremely fast JavaScript linter written in Rust focusing on ease of use, customizability, and speed. RSLint helps you find and fix error-prone productions in your code as well as enforce good practices.

RSLint does not require Node (opens new window) and has prebuilt binaries for Windows, Mac, and Linux but you are free to compile the project from source to any target supported by Rust.
