eslint-plugin-compat is an ESLint plugin that helps prevent accidental use of browser APIs that are not supported by your target browsers. By specifying your desired browser compatibility targets, the plugin flags code using unsupported features, improving cross-browser compatibility. It helps ensure your JavaScript code works reliably across different browsers, leading to a better user experience and reducing potential errors. This is a valuable tool for projects aiming for broad browser support or adhering to specific compatibility standards.
