The Table of Contents extension and Variable Explorer in VSCode provide a more organized and efficient approach to navigating and manipulating Jupyter Notebooks by allowing users to quickly access and modify key aspects of their code, such as headings and variable values. The kernel plays a critical role in ensuring the accuracy and consistency of data displayed in these tools, as it is responsible for executing the code and updating the variable values in real time. Without a properly functioning kernel, the data displayed in the Table of Contents and Variable Explorer may be outdated or incorrect.
