About
What is WLJS
The notebook interface (or IDE) combines live code in Wolfram, JavaScript, and other languages. We provide GUI building blocks for user input/output, a subset of LaTeX for equations, Markdown for narrative text, and data-driven presentations.
Think of it as a multi-tool platform for research, experiments, or as a powerful sandbox where you can try out your ideas, write a story about them, and then publish them on the web.
WLJS Notebook is the first open-source solution to feature true 2D math input combined with powerful syntax sugar and the most advanced support of interactive evaluation.
