Coding conventions are a set of guidelines that help programmers write code in a consistent and readable manner. These conventions cover various aspects, such as naming variables, formatting code, and organizing files. By following these rules, developers can make their code easier to understand and maintain, which is especially important when working in teams or on large projects. Adhering to coding conventions can also improve collaboration among developers. When everyone uses the same style, it becomes simpler to review each other's work and spot errors. Popular languages like Python, Java, and JavaScript each have their own established conventions, making it essential for programmers to familiarize themselves with the standards relevant to their chosen language.
