Pattern Matching with Match
Rust's match expression is a powerful control flow tool that allows you to compare a value against a series of patterns and execute code based on which pattern matches. It is similar to switch statements in other languages but much more powerful. The underscore _ pattern acts as a catch-all for any value that doesn't match previous patterns.

Breakdown
1
match number {
Starts a match expression on the number variable
2
1 => println!("One"),
If number equals 1, prints One
3
4..=10 => println!("Between four and ten"),
Range pattern matching numbers 4 through 10
4
_ => println!("Something else"),
Default case that catches all other values
