Python (Flask) vs JavaScript vs PHP [1B] Build Your First Web App!

Your First Web Apps: Build with Python, JavaScript & PHP: Flask, Express, Vanilla PHP. FAST Backend Dev Crash Course | Python ⚡ JavaScript ⚡ PHP (Part 1B: Build Your First Web App Step by Step).

Now that your environment is set up (from our last video!), it's time to write some code! In this hands-on tutorial, we'll guide you through building a simple "Hello World" web application in Python (using Flask), JavaScript (using Express.js), and PHP.
*
In this video, you will learn how to:
- Create a simple Flask app in Python.
- Build a lightweight Express.js app in JavaScript.
- Write and run a basic PHP script.
➡️ Next Steps: In our next video, we'll dive into the core concepts of variables and data types!

Python vs JavaScript vs PHP - Build Your First Web App (Flask, Express, Vanilla PHP).
Now that your environment is ready (watch Part 1 here: https://youtu.be/LJbnQvm6Rks ), let's code! In this hands-on tutorial, we build simple "Hello World" web applications using a framework for Python and JavaScript, and vanilla PHP. It's the ultimate showdown: which language gets a server running fastest?

🔥 What you'll build:
✅ A simple web server with Python using the Flask framework.
✅ A backend server with JavaScript using the Express.js framework in Node.js.
✅ A dynamic "Hello World" page with bare PHP.

You'll learn the basic anatomy of a backend application, including:
• Importing packages/modules
• Creating an application instance
• Setting up routes (URL paths)
• Starting a local development server
• Handling requests and sending responses

This is the perfect project to demystify how backend code powers websites!

Time to build! In this hands-on backend tutorial, we’ll use Python, JavaScript (Node.js), and PHP to create real web apps while mastering Object-Oriented Programming (OOP). Follow along as we build, explain, and code step by step.

By the end, you’ll understand how OOP powers backend development—and you’ll have a working project you can showcase!
