LaTeX
LaTeX is a high-quality typesetting system used for creating professional documents, particularly in academia and technical fields. It is based on the TeX typesetting language and allows users to focus on content while handling formatting automatically through markup commands. It excels at producing complex documents with mathematical formulas, citations, and structured layouts.
Developers should learn LaTeX when creating technical reports, research papers, theses, or documentation that requires precise formatting, mathematical notation, or bibliographies. It is essential in fields like mathematics, computer science, and engineering for its ability to handle complex equations and automate references, ensuring consistency and professional output. Use it for documents where content structure and typographic quality are prioritized over WYSIWYG editing.
