TypeScript Decorators

Introduction

Example

1/* this uses a decorator */
2@LogClassCreation
3class UserProfile {
4  constructor() {
5    console.log("Profile created");
6  }
7}

Key Points

• Decorators always start with the `@` symbol.
• They are an advanced, experimental TypeScript feature.
• You must enable them manually in the `tsconfig.json` file.
• They are essentially just functions that wrap other functions.
