Functions: Your Own Commands
Functions are reusable blocks of code that perform specific tasks. They're like teaching your cat a new trick:
```javascript function meow(times) { for (var i = 0; i < times; i++) { console.log("Meow!"); } }
meow(3); // This will print "Meow!" three times ```
Built-in Functions
JavaScript comes with many built-in functions. For example,
console.log()is a function that prints things to the console:javascript console.log("I'm a cat!");Loops: Repeating Tasks
Loops allow you to repeat a task multiple times without writing the same code over and over. It's like telling your cat to chase its tail for a specific number of rounds:
javascript for (var i = 0; i < 5; i++) { console.log("Chasing tail, round " + (i + 1)); }This will print "Chasing tail, round X" five times, where X goes from 1 to 5.
