What is the difference between function declarations and function expressions in JavaScript?

What is the difference between function declarations and function expressions in JavaScript?

Function declarations are defined using the 'function' keyword followed by a name, while function expressions can be anonymous and are assigned to variables.

Can you give me an example of each?

Sure! A function declaration looks like this:

function myFunction() {
  // code here
}

A function expression looks like this:

const myFunction = function() {
  // code here
};

Are there any differences in how they are hoisted?

Yes, function declarations are hoisted, meaning you can call them before they are defined. Function expressions are not hoisted.

What about arrow functions? Are they considered expressions?

Yes, arrow functions are a type of function expression. They provide a more concise syntax and do not have their own 'this' context.
