Adding objects to an array in JavaScript is a common task that can be done in a few different ways. One popular method is to use the push() method, which allows you to add new items to the end of an array. Here's a simple example of how to push objects into an array in JavaScript:

var myArray = []; // Create an empty array

var myObject1 = { name: 'John', age: 30 }; // Create an object

var myObject2 = { name: 'Jane', age: 25 }; // Create another object

myArray.push(myObject1); // Push the first object into the array

myArray.push(myObject2); // Push the second object into the array

console.log(myArray); // Output the resulting array

In this example, we create an empty array called myArray and two objects called myObject1 and myObject2. We then push these objects into the array using the push() method. The resulting array will contain both objects in the order in which they were pushed.

It's important to note that push() modifies the original array and returns the new length of the array. If you want to add multiple objects to an array, you can also use the concat() method or the spread operator (...) to merge two arrays.

Another important consideration when pushing objects into an array is that you are actually pushing a reference to the object, not a new copy of the object. This means that if you later modify the original object, the changes will also be reflected in the array. If you want to avoid this behavior, you can create a new copy of the object before pushing it into the array.

In summary, pushing objects into an array in JavaScript is a straightforward process using the push() method. By understanding how the method works and the potential side effects, you can efficiently manage arrays of objects in your JavaScript applications.
