What is "functions" in JavaScript?
A function is a block of code that performs a particular task.
A JavaScript function is executed when "something" invokes it (calls it).

‘Function Invocation (Calling)’ in JavaScript?
The code inside the function will execute when "something" invokes (calls) the function:
1. When an event occurs (when a user clicks a button)
2. When it is invoked (called) from JavaScript code
3. Automatically (self invoked)

Advantages of Functions?
1. Function makes the code reusable.
2. Define the code once, and use it many times.
3. Function increases readability.
4. You can use the same code many times with different arguments, to produce different results.
5. Function makes the program easier as each small task is divided into a function.
