Question
The following TypeScript code has an error. Can you identify and correct it?class Animal { constructor(public name: string) {}}let dog = new Animal();console.log(dog.name);What is the error, and how would you correct it?
Solution
The error in the TypeScript code is that the Animal class constructor expects one argument - name, but when creating a new Animal instance (let dog = new Animal();), no arguments are passed.
To correct this error, you need to pass a string argument when creating a new Animal instance. Here's the corrected code:
class Animal {
constructor(public name: string) {}
}
let dog = new Animal('Dog');
console.log(dog.name);
In this corrected code, 'Dog' is passed as an argument when creating a new Animal instance.
