what is you-dont-need-momentjs fr?

You Don't Need Moment.js is a reference guide for JavaScript developers who want to stop relying on Moment.js for date and time work. Moment.js is a widely used library but has two significant drawbacks: it does not support tree-shaking, which means bundlers cannot remove the parts you don't use, leading to a bundle size around 230 kB even for simple uses. It also uses a mutable API, where operations like adding five days change the original date object in place rather than returning a new one, which is a known source of bugs. The main content of the repository is a side-by-side comparison of date operations in Moment.js versus several alternatives: native JavaScript browser APIs, date-fns, dayjs, and Luxon. Each section covers a specific task, such as parsing a date string, formatting a date for display, adding or subtracting time, comparing two dates, or checking whether a date falls within a range. The Moment.js code and the alternatives appear next to each other for easy comparison. A summary table near the top of the README compares the alternatives on factors like tree-shaking support, number of supported locales, bundle size, and timezone handling. This is intended to help you choose the right replacement for your situation rather than prescribing one answer. An ESLint plugin ships with the project. ESLint is a tool that checks your JavaScript code as you write it. The plugin can flag any Moment.js usage in your codebase and suggest equivalent code in one of the alternatives, which makes a gradual migration easier to manage. The full README is longer than what was shown.
