Semantic naming is a practice in programming and software development where names are chosen to clearly convey the purpose and meaning of variables, functions, or classes. This approach helps developers understand the code more easily, as descriptive names provide context about what each element does, reducing confusion and improving readability. By using semantic naming, teams can enhance collaboration and maintainability of their code. For example, instead of naming a variable x, a developer might use totalPrice to indicate that it stores the total cost of items. This clarity aids both current and future developers in navigating the codebase efficiently.
