Objects can receive an Array Object as input by defining a property or method on the object that accepts an Array Object as an argument.

For example, consider the following object:

let myObject = {
  myMethod: function(myArray) {
    console.log(`Received array: ${myArray}`);
  }
};

This object has a method called myMethod that takes an array as an argument. To pass an array to this method, you can simply call the method and pass in the array as a parameter:

let myArray = [1, 2, 3];
myObject.myMethod(myArray); // Output: Received array: 1,2,3

Alternatively, you can define a property on the object that holds an array:

let myObject = {
  myArray: [],
  myMethod: function() {
    console.log(`Received array: ${this.myArray}`);
  }
};

In this case, you can set the value of the myArray property directly:

myObject.myArray = [1, 2, 3];
myObject.myMethod(); // Output: Received array: 1,2,3
