How do I ensure that all contributors follow consistent code formatting rules in a JavaScript project?

Consistent code formatting in a JavaScript project can be enforced using tools like ESLint or Prettier. Start by configuring ESLint with a shared set of rules for your team, but make sure that all team members use the same ESLint configuration. Additionally, integrate Prettier into your project, which will automatically format code to adhere to the specified rules.

Also, configure your code editor to run ESLint and Prettier on each file save to catch formatting issues early. Last but not least, make sure to incorporate code formatting checks into your CI/CD pipeline to prevent code with formatting issues from being merged into the codebase.
