Did you know in Rust, variables are immutable by default?

By default Rust variables are immutable.

In Rust, variables are immutable by default. It means once we give the variable a value, the value won't change.


The variable can be declared mutable with "mut" keyword.


e.g. let people = 10; // immutable


e.g. let mut people = 10; // mutable
