How to create a class in TypeScript?

Published April 16, 2022

To create a class, you can use the keyword class followed by using the {} symbol (opening and closing curly brackets) in TypeScript.

For example, let's say we need to make a class called Person with 2 fields like name and age.

It can be done like this,

// a simple class with 2 fields
class Person {
  name: string;
  age: number;
}

Now to make an instance of the above Person class, we can use the new keyword followed by invoking the Person class using the () symbol (brackets).

It can be done like this,

// a simple class with 2 fields
class Person {
  name: string;
  age: number;
}

// make an instance of the `Person` class
const person = new Person();

See the above code live in codesandbox.
