What are some tips for writing clean JavaScript code?

Here are some tips for writing clean JavaScript code: 1. Use meaningful variable names. 2. Keep functions small and focused. 3. Use consistent indentation and formatting. 4. Avoid global variables. 5. Comment your code where necessary.

Can you explain why meaningful variable names are important?

Meaningful variable names improve code readability and maintainability. They help other developers (and your future self) understand the purpose of a variable without needing extensive comments.

What do you mean by keeping functions small and focused?

Keeping functions small and focused means that each function should perform a single task or responsibility. This makes your code easier to test, debug, and reuse.

How can I ensure consistent indentation and formatting?

You can use code linters and formatters like ESLint and Prettier. They help enforce coding standards and automatically format your code.

Any tools you recommend for checking code quality?

Yes! Tools like ESLint for linting, Prettier for formatting, and JSHint for checking code quality are great options.
