🔗 TypeScript enums: Usage, advantages, and best practices

TypeScript enums offer a strong method to group and name associated constants in your applications.

Hardcoding user roles, API statuses, or application states can make your code harder to maintain and more prone to errors, especially when developing larger applications. A single typing mistake or minor alteration in your programming code can disrupt all the application’s functions.

TypeScript enums enable you to give clear and organized names to numerical values. You can define strings and numbers only once, then refer to them everywhere in the code.

This guide explains how enums work, the different types available, and when to use them. It also covers their limitations and when union types or object literals might be the better choice.
