What is linting and how does it work in different programming languages?

Linting is the process of analyzing code for potential errors and stylistic issues. Different programming languages have their own linting tools, like ESLint for JavaScript, Pylint for Python, and RuboCop for Ruby.

Can you explain how ESLint works for JavaScript?

ESLint analyzes JavaScript code to find problems based on predefined rules. You can customize these rules in a configuration file, and it helps maintain code quality and consistency.

Are there any specific linting rules that are commonly used?

Yes, common linting rules include enforcing consistent indentation, preventing the use of undeclared variables, and ensuring proper use of semicolons.

How can I set up linting in my project?

To set up linting, you typically need to install the linting tool via a package manager, create a configuration file, and then run the linter on your codebase.
