JavaScript Functions

There's another way to create functions - by storing them in variables! It's like putting a recipe card in a labeled box.

Function expression syntax:

const myFunction = function(parameters) {
  // Instructions go here
};

Key differences from declarations:

• •The function is stored in a variable
• •You MUST create it before using it (no hoisting)
• •The function itself doesn't need a name (anonymous)
• •Treated like any other value in JavaScript

Why use function expressions?

• •When you need to pass a function as a value
• •For one-time use functions
• •When the function is closely tied to a specific variable
• •Great for event handlers (like button clicks)

Think of function expressions as "portable" functions - you can pass them around and store them just like numbers or strings!
