Typescript Object

Typescript object

TypeScript is a superset of JavaScript that adds static types. It helps in building robust applications by catching errors at compile time rather than at runtime. Here’s how to create an object in TypeScript: You can define a type or interface to specify the shape of the object, allowing for better type safety.

interface Person {
    name: string;
    age: number;
    isEmployed: boolean;
}

const person: Person = {
    name: 'Alice',
    age: 30,
    isEmployed: true
};

You can also use class syntax to define objects. Classes provide a clearer structure for objects and can include methods as well. This is especially useful for object-oriented programming paradigms in TypeScript.

class Employee {
    name: string;
    age: number;
    position: string;

    constructor(name: string, age: number, position: string) {
        this.name = name;
        this.age = age;
        this.position = position;
    }

    displayInfo() {
        return `${this.name}, ${this.age} - ${this.position}`;
    }
}

const employee = new Employee('Bob', 28, 'Developer');
console.log(employee.displayInfo());

In addition to defining objects with interfaces and classes, you can also create objects on the fly using inline object notation, which is straightforward but doesn’t provide as much type checking. This approach is handy for simple structures.

const user = {
    username: 'john_doe',
    isActive: true,
    login() {
        console.log(`${this.username} has logged in.`);
    }
};

user.login();
