Functions in JavaScript.

Summary
Functions are the fundamental building blocks in JavaScript. It is a set of instructions to perform a particular action/ task. We've started the discussion - why do we need functions in the first place and the benefits of using JavaScript functions. It is important to know these basics, unfortunately, I don't see anyone explain these concepts.

There are two ways to define a JavaScript function, function declaration and Function Expression. we've compared and contrast them with examples. Parameters are the variables that accept values within a function from outside. The values that we pass to a function are called Arguments. To return values from a function, we have the 'return' keyword.
