JupyterLab
JupyterLab is an interactive development environment (IDE) for working with Jupyter notebooks, code, and data. It provides a web-based interface that integrates notebooks, text editors, terminals, and custom components in a flexible layout, enabling data science, scientific computing, and machine learning workflows. It is the next-generation interface for Project Jupyter, succeeding the classic Jupyter Notebook.
Developers should learn JupyterLab for data exploration, prototyping, and interactive computing tasks, especially in fields like data science, machine learning, and research. It is ideal for creating and sharing documents that combine live code, equations, visualizations, and narrative text, facilitating reproducible analysis and collaboration. Use it when working with Python, R, or Julia for iterative development, data visualization, and educational purposes.
