type inheritance typescript code example
Example 1: typescript class interface
interface IPerson {
name: string
age: number
hobby?: string[]
}
class Person implements IPerson {
name: string
age: number
hobby?: string[]
constructor(name: string, age: number, hobby: string[]) {
this.name = name
this.age = age
this.hobby = hobby
}
}
const output = new Person('john doe', 23, ['swimming', 'traveling', 'badminton'])
console.log(output)
Example 2: classes in typescript
class Info {
private name: string ;
constructor(n:string){
this.name = n ;
};
describe(){
console.log(`Your name is ${this.name}`);
}
}
const a = new Info('joyous');
a.describe();
Example 3: class inheritance in typescript
class Info {
protected name: string ;
constructor(n:string){
this.name = n ;
};
describe(){
console.log(`Your name is ${this.name}`);
}
}
class Detail extends Info{
constructor(name:string, public age:number){
super(name);
}
findAge(){
console.log(`${this.name} age is ${this.age}`)
}
}
const b = new Detail('jank', 23);
b.describe();
b.findAge();
