Helpppppp !!! - TypeScript

What is TypeScript?

TypeScript is a superset of JavaScript developed by Microsoft. It adds optional static typing, class-based object-oriented programming, and other features to JavaScript.

Why use TypeScript?

Using TypeScript can help catch errors before runtime, as well as provide better code organization and maintainability through object-oriented programming concepts.

How to get started with TypeScript?

To start using TypeScript, first install the TypeScript compiler using npm install -g typescript. Then, create a .ts file and run tsc filename.ts to compile it into JavaScript.

Some basic TypeScript syntax:

// Static typing
let variableName: string = "Hello World"; 

// Classes and Inheritance
class Animal {
  speak() {
    console.log("Animal makes a noise");
  }
}

class Cat extends Animal {
  speak() {
    console.log("Cat meows");
  }
}

let myAnimal: Animal = new Cat();
myAnimal.speak(); // Prints "Cat meows"

// Interfaces
interface Person {
  name: string;
  age?: number;
}

function greet(person: Person) {
  console.log(`Hello, ${person.name}`);
}

greet({ name: "John" }); // Prints "Hello, John"
