Array Types

Type arrays and their elements

Declare array types with type[] or Array<type>:

let numbers: number[] = [1, 2, 3];
let strings: Array<string> = ["a", "b"];

numbers.push(4);   // OK
numbers.push("5"); // Error: string not allowed

let mixed: (string | number)[] = [1, "two", 3];

Both syntaxes are equivalent.
