How to Dynamically Render Objects from an API in JavaScript

Working with APIs and dynamically displaying data on a web page can be daunting, especially when you're trying to filter through data based on user input. In this guide, we will explore how to dynamically render objects from an API response in JavaScript.

The Problem: Rendering Dynamic Data

Imagine you have an array of objects fetched from an API. Your goal is to let users enter the name of an object into an input field, and based on this input, the corresponding properties of that object should be displayed in specific HTML elements.

For example, if a user types "Name 1", the app needs to find this object in the array and then populate HTML elements with the object's corresponding properties.

The Solution: Step-by-Step Guide

Step 1: Fetching the Data

First, you need to have your data (array of objects) ready. This data can be fetched from an API, but for simplicity, we will create a sample array.
