The video tutorial explains the differences between function declarations and function expressions in JavaScript. It covers how to declare functions using the 'function' keyword and how to create function expressions by assigning functions to variables. The concept of hoisting is introduced, explaining how function declarations are available before code execution, unlike function expressions. Practical examples demonstrate these concepts, and recommendations for organizing code are provided.
