By calling a function, we can execute the code within the function body. This is useful because we can reuse the same code multiple times without having to repeat it in our program. We can also pass different arguments into the function each time we call it, which allows for even more flexibility in our programs.
To better understand how to call a function, let’s take a closer look at the syntax. First, we declare our function using the function keyword, followed by the function name and parentheses. Inside the parentheses, we can specify any parameters that the function will accept. Then, we define the function body using curly braces. Within the function body, we can execute any code that we want the function to perform.
Once we have defined our function, we can call it by using its identifier, followed by parentheses. Inside the parentheses, we can specify any arguments that we want to pass into the function. When the function is called, it will execute the code within its body, using the arguments we passed in (if any).
