JavaScript for Beginners: A Crash Course

Hey there! 👋
I’m JavaScript—you might’ve heard of me. I’m the cool programming language that powers websites, apps, and even servers. But instead of someone else hyping me up, let me introduce myself!

1. I’m a High-Level Language

Think of me as a friend who explains complex stuff in simple terms. Writing code with me is like having a casual chat—super easy and intuitive!

Simple vs. Complex Code

2. I’m Just-In-Time Compiled

I’m a fast learner! I compile code while running it, so you don’t need to wait. Like a chef cooking your meal fresh as you order.

JavaScript compiling code like a chef preparing your order fresh!

3. I Follow ECMAScript Rules

Think of ECMAScript as my rulebook. It ensures I behave the same way on Chrome, Firefox, Safari, and beyond.
No matter the browser, I’m your consistent web companion. 💻

JavaScript work the same, no matter the browser!

4. I’m Dynamically Typed

Need me to be a number one moment and a string the next? No problem! I’m flexible like that.
Here’s an example of my versatility:
