Code Formatting

Code formatting is the practice of applying consistent stylistic rules to source code, such as indentation, spacing, line breaks, and naming conventions, to improve readability and maintainability. It is typically enforced through automated tools like linters or formatters that parse and rewrite code according to predefined or configurable standards. This concept is fundamental in software development to ensure code is clean, uniform, and easier to collaborate on across teams.

Also known as: Code Style, Code Beautification, Source Code Formatting, Pretty Printing, Auto-formatting

Why learn Code Formatting?

Developers should learn and use code formatting to reduce cognitive load, prevent style-related merge conflicts, and adhere to team or project standards, especially in collaborative environments. It is critical in large codebases, open-source projects, and when working with languages like Python (where indentation affects execution) or JavaScript (where inconsistent styles can lead to bugs). Automated formatting tools save time by eliminating manual style adjustments and enforcing best practices.
