Effortlessly convert code from go to typescript in just 3 easy steps. Streamline your development process now.
npm install -g typescript
Setting Up a Project
Create a new directory for your project and navigate into it:
mkdir my-typescript-project
cd my-typescript-project
Initialize a new Node.js project:
npm init -y
Install TypeScript as a development dependency:
npm install typescript --save-dev
index.ts
and add the following code:
function greet(name: string): string {
return `Hello, ${name}!`;
}
console.log(greet("World"));
Compiling TypeScript
To compile your TypeScript code to JavaScript, run the following command:
npx tsc index.ts
This will generate an index.js
file that you can run using Node.js:
node index.js
interface Person {
name: string;
age: number;
}
const person: Person = {
name: "John",
age: 30
};
Generics
Generics allow you to create reusable components. They provide a way to create functions, classes, or interfaces that work with different types.
function identity<T>(arg: T): T {
return arg;
}
console.log(identity<number>(5));
console.log(identity<string>("Hello"));
function log(target: any, key: string) {
console.log(`${key} was called`);
}
class Calculator {
@log
add(a: number, b: number): number {
return a + b;
}
}
const calculator = new Calculator();
calculator.add(2, 3);
npm install -g typescript
.
Is TypeScript better than JavaScript?
TypeScript offers several advantages over JavaScript, such as static typing, better tooling, and improved code quality. However, it ultimately depends on the project requirements.
Yes, TypeScript can be used with React. It provides type-checking and autocompletion, making the development process smoother.
How do I compile TypeScript?You can compile TypeScript using the TypeScript compiler (tsc). Run the command npx tsc <filename>.ts
to compile your TypeScript code to JavaScript.
TypeScript is a powerful tool that enhances JavaScript by adding static types. It improves code quality, offers better tooling, and makes collaboration easier. Whether you are a beginner or an experienced developer, TypeScript can help you write more reliable and maintainable code.
By following this guide, you can start your journey with TypeScript and take advantage of its powerful features. Happy coding!
