What does a standard function look like?

A standard function in programming typically has a specific structure. Here's a step-by-step breakdown of what it looks like:

1. Function Name: This is the identifier by which the function can be called. It should be descriptive of what the function does.

2. Parameters: These are the inputs to the function. They are placed within the parentheses after the function name. A function can have zero, one, or multiple parameters.

3. Function Body: This is the block of code that runs when the function is called. It is enclosed within curly braces {}.

4. Return Statement: This is the output of the function. Not all functions need to return something, but if a function does, it uses the return keyword.

Here's an example of what a standard function might look like in JavaScript:

function addNumbers(num1, num2) {
  var sum = num1 + num2;
  return sum;
}

In this example, addNumbers is the function name, num1 and num2 are the parameters, the function body calculates the sum of num1 and num2, and then that sum is returned by the function.
