Markdown
Markdown is a lightweight markup language with plain-text formatting syntax that can be converted to HTML and other formats. It is designed to be easy to read and write, allowing users to create formatted text using simple, intuitive symbols like asterisks and hash signs. Markdown is commonly used for documentation, readme files, forum posts, and note-taking due to its simplicity and wide support across platforms.
Developers should learn Markdown for creating clear, readable documentation, writing technical blog posts, and formatting content in version control systems like Git (e.g., for README.md files). It is essential for collaborative projects on platforms like GitHub, GitLab, and in tools like Jupyter Notebooks, as it enables quick formatting without the complexity of HTML, improving productivity and communication in development workflows.
