How to Use AI Tools to Write Your First JavaScript Program in 1 Hour

If you're a beginner looking to dip your toes into programming, the thought of writing your first JavaScript program can feel daunting. But what if I told you that you could leverage AI tools to get your first program up and running in just one hour? In 2026, AI has evolved to be incredibly helpful for coding novices, making the learning curve a lot less steep.

I’ve experimented with several AI coding tools, and today, I'll guide you through using them effectively. We'll focus on the tools that can help you write your first JavaScript program, troubleshoot common errors, and even learn along the way.

Prerequisites: What You Need to Get Started

Before we dive in, ensure you have the following:

  1. A Computer: Any computer that can run a web browser.
  2. Code Editor: Install Visual Studio Code (VS Code) - it's free and popular among developers.
  3. Basic Understanding of Programming Concepts: Familiarity with variables, loops, and functions will be helpful, but not mandatory.

Here’s a list of AI tools that can help you write your first JavaScript program. I've included what they do, pricing, and limitations.

| Tool Name | Pricing | Best For | Limitations | Our Take | |------------------|----------------------------|--------------------------------|--------------------------------------|----------------------------------| | GitHub Copilot | $10/mo, free trial available| Code suggestions and completions| Limited to supported languages | We use it for quick code snippets. | | ChatGPT | Free tier + $20/mo pro | Generating code and explanations| May generate incorrect code | Great for understanding concepts. | | Codeium | Free, $19/mo for pro | Code completion and suggestions | May lack context in complex scenarios | We use it for faster coding. | | Replit | Free tier + $7/mo pro | Collaborative coding environment| Limited features in free tier | Good for experimenting with code. | | Tabnine | Free, $12/mo for pro | Smart code completions | Can be hit or miss with suggestions | We find it useful for repetitive tasks. | | Polypane | $15/mo, free trial available| Testing responsive designs | More design-focused, not coding | We don’t use it for coding directly. | | Sourcery | Free, $12/mo for pro | Code refactoring and suggestions| Limited to Python primarily | Not applicable for JavaScript. | | CodeGPT | $9/mo, no free tier | AI-powered coding assistance | Less popular, may have fewer features| We don't use it due to limited support. | | DeepCode | Free, $20/mo for pro | Code reviews and bug detection | Limited language support | Not ideal for beginners. | | Codex | $0.01 per token | Natural language to code | Pricing can get high with usage | Useful for generating specific code snippets. | | AI Dungeon | Free, $10/mo for pro | Interactive code storytelling | Not focused on real coding | Skip unless you want a fun twist. | | Snippet Generator | Free | Quick code snippets | Very basic, lacks advanced features | We use it for quick references. | | Jupyter Notebook | Free | Interactive coding and learning | Requires Python knowledge | Not directly useful for JavaScript. |

What We Actually Use

For writing our first JavaScript program, we recommend using GitHub Copilot for code suggestions and ChatGPT for generating explanations. Together, they create a powerful learning environment.

Step-by-Step Guide to Writing Your First JavaScript Program

Step 1: Setup Your Environment

  • Install Visual Studio Code: Download and install VS Code from here.
  • Install GitHub Copilot: Follow the instructions to set it up in VS Code.
  • Open a New File: Create a new JavaScript file (e.g., hello.js).

Step 2: Write Your First Program

  1. Use Copilot: Start typing console.log( and wait for Copilot to suggest the completion.

  2. Input Text: Type in a simple message, like "Hello, World!".

  3. Complete the Line: Press Enter to accept the suggestion.

    Your code should now look like this:

    console.log("Hello, World!");
    

Step 3: Run Your Program

  • Open Terminal in VS Code: Go to View > Terminal.
  • Run the Command: Type node hello.js and hit Enter. You should see Hello, World! printed in the terminal.

Troubleshooting Common Issues

If you encounter errors, here’s what you can do:

  • Syntax Errors: Double-check your code for typos. Copilot can sometimes generate incorrect syntax.
  • Node Not Installed: If you see an error saying node: command not found, install Node.js from here.

What’s Next?

Once you’ve successfully run your first program, consider building upon it. Here are a few ideas:

  1. Create a Simple Calculator: Use functions to add, subtract, multiply, and divide.
  2. Learn About Variables: Use variables to store user input and display results.
  3. Explore Loops and Conditionals: Write programs that make decisions based on user input.

Conclusion: Start Here

Using AI tools significantly lowers the barrier to entry for beginners learning JavaScript. By leveraging GitHub Copilot and ChatGPT, you can quickly write and understand your first program.
