JSLint
JSLint is a static code analysis tool for JavaScript that enforces a strict set of coding standards and best practices. It scans JavaScript code for potential errors, stylistic issues, and problematic patterns, helping developers write cleaner and more reliable code. Originally created by Douglas Crockford, it serves as a linter to improve code quality and maintainability.
Developers should use JSLint when working on JavaScript projects that require high code quality, consistency, and adherence to specific coding conventions, such as in enterprise applications or open-source libraries. It is particularly useful for catching syntax errors, enforcing coding standards, and preventing common bugs early in the development process, which can reduce debugging time and improve team collaboration.
