How to generate an array using an interface?

edit

To generate an array using an interface, you can do the following:

1. Define the interface. For example:

interface Person {
  name: string;
  age: number;
}

1. Create an array of objects that implement the interface. For example:

const people: Person[] = [
  { name: "John", age: 30 },
  { name: "Jane", age: 25 },
  { name: "Bob", age: 40 }
];

This creates an array of Person objects with different values for the name and age properties.

1. You can also generate the array dynamically using a function. For example:

function generatePeople(numPeople: number): Person[] {
  const people: Person[] = [];
  for(let i = 0; i < numPeople; i++) {
    people.push({
      name: `Person ${i}`,
      age: Math.floor(Math.random() * 50) + 20 // generate a random age between 20 and 69
    });
  }
  return people;
}

const people = generatePeople(5); // generates an array of 5 Person objects with random names and ages

This function generates a specified number of Person objects with random names and ages, and returns them as an array.
