Sometimes, we want to create model classes in TypeScript.

In this article, we’ll look at how to create model classes in TypeScript.

How to create model classes in TypeScript?

To create model classes in TypeScript, we can create interfaces.

For instance, we write

interface IDonutChartModel {
  dimension: number;
  innerRadius: number;
}

const donut: IDonutChartModel = {
  dimension: 1,
  innerRadius: 2,
};

to create the IDonutChartModel interface.

Then we create the donut variable of type IDonutChartModel and assign it an object with content that matches the properties and data types of each property listed in the IDonutChartModel interface.
