### 1.1. History

* *IPython Notebook* (2011)
  * Only support *Python*
* *Jupyter Notebook* (2014)
  * Supporting *Python*, *R* and *Julia* languages, etc.
* *JupyterLab* (2018)
  * Extensions supported (2019)
  * Added IDE features, e.g. Debugger (2021)

### 1.2. Differences between Sub-projects

* **IPython** is an interactive shell for Python and **a kernel for Jupyter**.
* **IPython Notebook** Predecessor of *Jupyter Notebook*, only support *Python*.
* **Jupyter Notebook** is a web-based interactive computing environment for creating and sharing documents containing code and text, supports multiple languages.
* **JupyterLab** is the *next-generation* user interface for *Jupyter Notebook*, offering enhanced features and flexibility for interactive computing workflows.

#### 2.3.1. Features of JupyterLab

* It provides an enhanced and more flexible environment for working with notebooks, text files, terminals, and other interactive features.
* JupyterLab offers a **multi-tabbed** interface, allowing you to work with multiple notebooks and files simultaneously. It also includes a flexible layout system, enabling you to arrange and organize various components within the user interface.
* JupyterLab retains all the features of Jupyter Notebook and introduces additional capabilities, making it a more powerful and extensible environment for interactive computing.

## 3. Install
