Typescript Type Vs Enum One thing to consider is maintainability if the values of the strings are subject to change then using a string enum means only changing 1 string literal whereas using a string type means changing them everywhere they re used

Enums are one of the few features TypeScript has which is not a type level extension of JavaScript Enums allow a developer to define a set of named constants Using enums can make it easier to document intent or create a set of distinct cases TypeScript provides both numeric and string based enums Here s how you can define an enum in TypeScript enum Direction Up UP Down DOWN Left LEFT Right RIGHT Key Differences Between Type and Enum Purpose Type Used for defining the shape of data and ensuring type safety Enum Used for defining a set of named constants Usage Type Applied to variables function parameters

When deciding between using an enum or a type in TypeScript consider the nature of the data you are working with Use enums for a distinct set of related constants that are fixed and known at compile time On the other hand use types when you need to define complex data structures or create reusable aliases for existing data types In TypeScript choosing between enums types and interfaces can be perplexing Each serves a distinct purpose but understanding their differences and when to use them is crucial for writing clean and maintainable code

In TypeScript enum and type are two constructs that allow you to define named constants and type aliases respectively An enum short for enumeration is a way to group a set of related values under a single name typically used to represent a fixed set of options When working with TypeScript understanding the differences between enums and types is crucial for writing maintainable and scalable code Both enums and types serve different purposes and have their own unique features
