TypeScript Classes

Introduction

Example

1/* this creates a typed class */
2class Player {
3  name: string;
4  score: number;
5
6  constructor(playerName: string) {
7    this.name = playerName;
8    this.score = 0;
9  }
10}

Key Points

• You must declare all properties at the top of the class.
• The `constructor` initializes the actual data.
• Methods inside the class also require strict types.
• It prevents missing properties when creating new objects.
