🚀Day 38 of My Internship: Understanding var, let, and const in JavaScript! 🚀💻
Today, I dived into the world of JavaScript variables and learned the key differences between var, let, and const, especially in terms of scope and usage.
var: 🌍 Function-scoped and hoisted, but can lead to bugs if not carefully managed.
let: 📦 Block-scoped, meaning it’s confined to the block where it’s defined. Safer to use in modern JavaScript as it prevents re-declaration within the same scope.
const: 🔒 Block-scoped and immutable after declaration—ideal for constants that shouldn’t change.
I also wrote a program to demonstrate the behavior of each variable, which helped deepen my understanding! 💡
Always excited to learn new concepts and level up my coding skills! 💪
