Strong types in programming languages like C++ and Rust, which enforce specific data types and rules for variables, lead to fewer bugs, more expressive APIs, and potentially better performance. They prevent invalid input, improve code clarity, and reduce the need for repetitive error checking (like in JavaScript with undefined).

Some programmers tried to standardize Markdown with CommonMark, but Markdown's lack of a single standard is actually its strength.
