The decodeJupyterNotebook function decodes the content of a Jupyter Notebook file by reading it into a string, parsing it as JSON, and logging the content of code cells. It takes a single argument, filePath, which is the path to the Jupyter Notebook file, and raises an error if there are any issues with file reading or parsing.

    fs.readFile(filePath, 'utf8', (err, data) => {

            return;

Function: decodeJupyterNotebook

Description

Decodes the content of a Jupyter Notebook file.

Parameters

• filePath: Path to the Jupyter Notebook file to decode.

Functionality

1. Reads the file at filePath into a string using fs.readFile.
2. Parses the file content as JSON using JSON.parse.
3. Extracts the cells from the parsed notebook.
4. Iterates through the cells and logs the content of code cells.

Error Handling

1. Catches any errors that occur during file reading.
2. Catches any errors that occur during notebook parsing.

Usage

Call the decodeJupyterNotebook function with the path to a Jupyter Notebook file as an argument.

Example

decodeJupyterNotebook('Untitled.ipynb');
