Can a function be called multiple times within a single file?

Yes, a function can indeed be called multiple times within a single file, and this is a fundamental feature of programming in most languages, including JavaScript, Python, PHP, and many others. When you define a function, you establish a block of reusable code that can be executed whenever the function is invoked.

Calling a function multiple times is often done to perform repetitive tasks without needing to rewrite the same code. For example, if you have a function that calculates the sum of two numbers, you can call that function anytime you need a sum, providing different numbers each time. This promotes code reusability and maintainability.

Additionally, functions can be called from various places in the file, whether that's from other functions, directly in the main code, or even inside loops or conditional statements. This flexibility allows for more dynamic and efficient programming.

In summary, the ability to call a function multiple times within the same file enhances code efficiency and organization, making it a crucial aspect of programming.
