What Are Enums?
An enum (short for enumeration) is a data type that allows you to define a set of named constants. Enums are used to group related values together, making your code more organized and less error-prone.

enum Days {
Monday,
Tuesday,
Wednesday,

console.log(Days.Monday); // Output: 0
console.log(Days.Friday); // Output: 4
