Typescript: interface
interface Owner {
name: string;
gender: string;
}
interface Vehicle {
name: string;
year: Date;
broken: boolean;
owner: Owner;
summary: () => string;
}
const civic: Vehicle = {
name: "civic",
year: new Date(),
broken: true,
owner: { name: "yenonn", gender: "male" },
summary: function (): string {
return `summary: name ${this.name} year: ${this.year} broken: ${this.broken} owned by ${this.owner.name}`;
},
};
console.log(civic.summary());
There are different ways to write a function in typescript
//Method 1
function func0(age: number) {
console.log(age);
}
func0(0);
//Method 2
const func1 = (age: number) => {
console.log(age);
};
func1(1);
//Method 3
const func2 = function (age: number): void {
console.log(age);
};
func2(2);
//Method 4
const func3: (age: number) => void = function (age: number): void {
console.log(age);
};
func3(3);
//Method 5
const func4: (age: number) => void = (age: number): void => {
console.log(age);
};
func4(4);
