The video tutorial introduces the concept of comments in programming, specifically in Rust. It explains the importance of comments for code readability and maintenance. The tutorial covers different types of comments, including line comments, block comments, and doc comments, and demonstrates their usage in a Rust program. An exercise is provided for students to practice writing comments, encouraging them to reflect on their learning objectives and personal interests.
