LaTeX
LaTeX is a high-quality typesetting system used for creating professional documents, particularly in academia and technical fields. It uses markup language to separate content from formatting, enabling precise control over document layout, mathematical equations, citations, and complex structures like tables and figures. It is widely used for writing research papers, theses, books, and presentations.
Developers should learn LaTeX when working on technical documentation, academic writing, or projects requiring precise typography and mathematical notation, such as in mathematics, physics, computer science, or engineering. It is essential for creating publication-ready documents with consistent formatting, automated bibliography management via BibTeX, and handling complex equations that are difficult in standard word processors.
