How to Create an Array of Objects from HTML Element Values in JavaScript?

JavaScript is an incredibly versatile language, and one of its key strengths is the ability to dynamically manipulate HTML elements and their values. One common task is creating an array of objects from these element values. This can be especially useful for form handling, enabling the efficient collection and storage of user input.

Why Create an Array of Objects?

When dealing with forms or any set of HTML elements, it is often necessary to capture the data in a structured way. Arrays of objects provide a clean and organized method for storing this data, making it easier to manipulate, validate, and eventually send to a server if needed.

Steps to Create an Array of Objects

Here’s a simple guide to achieve this:

HTML Structure

Suppose we have a simple form with multiple input fields. Here’s an example:
