How can I effectively leverage Jspreadsheet to manage my spreadsheets in a more data-driven way and integrate a system that tracks and lists all the programming languages I use across various projects? I want to include specific details, such as the productivity level of each language, how frequently I use them, and the types of projects where each one is applied. Additionally, I’m interested in understanding how I could organize this data efficiently to provide clear insights and, if possible, connect it to a backend, like Django, so that the data remains updated in real-time. This would allow me to make more informed decisions, especially when it comes to selecting the most appropriate language for future projects based on historical usage and performance metrics. What would be the best practices for structuring this information to ensure that it is both practical and insightful in a data-driven context?
