What is the difference between enum and const in TypeScript?

In TypeScript, an enum is a special type that allows you to define a set of named constants. A const, on the other hand, is a way to declare a variable that cannot be reassigned.

Can you give me an example of how to use enums?

Sure! Here's a simple example:

enum Direction {
    Up,
    Down,
    Left,
    Right
}

let move: Direction = Direction.Up;

How do const variables work in TypeScript?

Const variables are declared using the const keyword and must be initialized at the time of declaration. They cannot be reassigned later. For example:

const PI = 3.14;

When should I use enums instead of const?

Use enums when you need a set of related constants that can be easily referenced and compared. Use const for single values that won't change.
