Understanding JavaScript Functions 🚀
📚 A function is a block of organized, reusable code used to perform specific actions or tasks.
Functions are the backbone of efficiency. They can encapsulate a set of instructions and be called or invoked multiple times throughout a program. This feature promotes code reuse, readability, and modularity, which are invaluable during development!
🔍 Example with console.log()
console.log() is a built-in function in JavaScript that allows you to log output to the console. You can use it to display messages, debug code, or perform various tasks.
