Now, you can use the has function in your TypeScript code by passing an object and a string key as arguments. The has function will return a boolean value indicating whether the object has the specified key or not.

Here's an example:

index.ts
interface Person {
  name: string;
  age: number;
  address: {
    city: string;
    street: string;
  };
}

const person: Person = {
  name: 'John Doe',
  age: 30,
  address: {
    city: 'New York',
    street: '123 Main St',
  },
};

console.log(has(person, 'name')); // Output: true
console.log(has(person, 'occupation')); // Output: false
console.log(has(person, 'address.city')); // Output: true

In the above example, the has function checks whether the person object has the name, occupation, and address.city keys. The first and third checks return true since the person object has those keys, while the second check returns false since the occupation key is not present in the person object.
