[[Rust]] The array notation is a bit special compared to other languages so I will write it down here: Unlike tuples, arrays can only hold one type: `let a: [i32; 5] = [1, 2, 3, 4, 5]` Specifies an array of length 5. `let a = [3; 5];` specifies an array of length 5 with all values set to 3. > Note the semicolon rather than a comma! Indexing as usual Out of bounds access result in a panic.
