What is a key naming convention for functions?

A key naming convention for functions is that a function name should be as descriptive as possible to indicate what the function does. This is important because descriptive names help other programmers (and your future self) easily understand the purpose and behavior of the function without needing to read through its implementation details. A well-chosen name provides clarity, making the code more maintainable and accessible, as it communicates intent effectively.

For instance, a function named calculateArea clearly indicates that its purpose is to compute the area of a certain shape, whereas a generic name like function1 does not provide any context. Good naming conventions enhance code readability and usability in collaborative environments, allowing developers to understand and use functions intuitively based on their names.

Other options do not align well with the principles of good naming conventions in programming. For instance, indicating the runtime of a function or requiring identical names for similar behavior could lead to confusion rather than clarity. Organizing function names alphabetically may help in locating them, but it does not contribute to understanding their functionality.
