Indentation
Indentation is a programming practice of adding whitespace (typically spaces or tabs) at the beginning of lines to visually structure code into blocks, such as loops, conditionals, and functions. It enhances code readability by making the logical hierarchy and scope of statements clear to developers. While not affecting program execution in most languages, it is often enforced by syntax rules in languages like Python.
Developers should learn and use indentation to write clean, maintainable code that is easy for humans to read and debug, especially in collaborative projects. It is essential in languages like Python, where indentation defines code blocks syntactically, and recommended in others like JavaScript or C++ to prevent errors and improve code review efficiency. Use cases include organizing nested control structures, function definitions, and class bodies.
