tuple and list look similar in typescript code example
Example 1: tuple angular
var employee: [number, string] = [1, "Steve"];
employee[0]; // returns 1
employee[1]; // returns "Steve"
Example 2: tuple in typescript
let empId: number = 1;
let empName: string = "Steve";
// Tuple type variable
let employee: [number, string] = [1, "Steve"];
