Javascript Output Issue in VSCode Jupyter Notebook
Are you facing difficulties getting Javascript to display output in your Visual Studio Code (VSCode) Jupyter Notebook? You're not alone! Many users have reported issues where they can run Python code successfully but struggle to see any output when executing Javascript code.
In this guide, we will explore the potential reasons for this output issue and provide you with a clear solution to get your Javascript code working in VSCode Jupyter Notebook.
Understanding the Problem
When you try to execute certain Javascript code in a Jupyter Notebook cell, you might expect to see output similar to that of Python. For instance, the Python code print("test") works perfectly, displaying "test" as output. However, using Javascript commands such as:

or

does not yield any output. This can be frustrating, especially if you are accustomed to Jupyter's interactive environment.
Why the Issue Occurs
The primary reason for this output issue is due to the way Jupyter handles different kernel environments:
Different Kernels: While the Jupyter Notebook does support multiple languages, each kernel might have different requirements for output display. The default Jupyter Notebook uses Python, and when attempting to run Javascript without the proper kernel, it may not produce output as expected.
Command Syntax: The syntax and commands you are using to execute Javascript might not be correct for the kernel.
Solution: Running Javascript in Jupyter with VSCode
To resolve the output issue when running Javascript in a Jupyter Notebook, you should use the following command instead:

Steps to Implement
Open Your Jupyter Notebook in VSCode: Ensure you have the correct Jupyter Notebook open in Visual Studio Code.
Create a New Cell: Insert a new cell in your notebook where you want to execute the Javascript code.
Use the Correct Syntax: Copy and paste the following code into your new cell:

Run the Cell: Execute the cell (typically by pressing Shift + Enter) to see the output.
Expected Outcome
After running the cell with the correct command, you should see the output as expected in the output section of the Jupyter Notebook. The command console.log("test"); will successfully print test, demonstrating that Javascript is running correctly in your environment.
Conclusion
By understanding the necessity of using the correct kernel and commands, you can effectively troubleshoot the issue with Javascript output in your VSCode Jupyter Notebook. Embrace your coding journey, and don't hesitate to experiment with different languages within this versatile environment.
If you follow the steps outlined above, you should be able to resolve your frustrations and harness the true power of Javascript in Jupyter Notebooks.
Happy coding!
