JavaScript: Functions As Values, A More Powerful Way To Do Functions

Описание: #javascript #webdev #programming #coding #softwareengineering #learntocode #js #webdevelopment

In this video, we dive into one of the most important concepts in JavaScript: functions are values. Unlike some other languages where functions are just a set of instructions, JavaScript treats them as "first-class citizens." This means you can assign them to variables, pass them as arguments to other functions, and even return them from functions.

Understanding this concept is key to mastering callbacks, higher-order functions, and functional programming patterns in modern web development. I break down exactly how this works under the hood and show you practical examples of how to use this feature to write cleaner, more flexible code.
