Markdown is a lightweight markup language used to format text in a plain text editor for easy conversion to HTML. It was originally created by John Gruber in 2004 as a way to write and format content for the web in a simple and readable way.

Markdown uses a syntax that is easy to remember and intuitive to use, with special characters and punctuation used to denote formatting elements such as headings, lists, bold and italic text, and links.

Why do we use markdown?

There are several reasons for using markdown as a developer. Here are few of them:

Easy to learn and use: Markdown is a simple markup language that is easy to learn and use, even for people with no prior programming experience. It has a simple syntax that is easy to remember, making it a popular choice for writers, bloggers, and content creators.

Platform-independent: Markdown files can be read and edited on any device or platform, as they are just plain text files. This makes it easy to collaborate with others who may be using different devices or software.

Universally compatible: Markdown files can be easily converted to HTML, PDF, or other formats, making them highly compatible with a wide range of tools and platforms.

Focus on content: Markdown allows writers to focus on the content, rather than worrying about formatting. It helps to keep the content simple, while still allowing for basic formatting and organization.
