typescript interface array code example

Example 1: typescript class implements interface

interface Task{
    name: String; //property
    run(arg: any):void; //method
}

class MyTask implements Task{
    name: String;
    constructor(name: String) {
        this.name = name;
    }
	run(arg: any): void {
        console.log(`running: ${this.name}, arg: ${arg}`);
    }
}

let myTask: Task = new MyTask('someTask');
myTask.run("test");

Example 2: typescript export interface array

interface Animal {  name: string;  size: "small";  medium;  large;}const animalsArray: Animal[] = [  { name: "chicken", size: "small" },  { name: "pig", size: "medium" },  { name: "cow", size: "large" },];

Example 3: create method in interface for set TS

running: someTask, arg: test
