A common desire among developers is to create UI elements that respond dynamically to user actions. A typical example is when a user selects a currency from a dropdown menu, and a button updates its text to reflect the selected currency. If you've encountered this challenge, you're not alone! In this post, we'll walk you through the solution step-by-step. The Problem Statement You want a button's text to change according to the currency selected from a dropdown menu. For instance, selecting "AUD" should change the button text to "AUD," while selecting "USD" should change it to "USD." Achieving this functionality in a React.js application can be straightforward if you utilize state properly. Solution Overview To implement this feature, we'll utilize React's useState hook to manage the button's text and the dropdown's open/closed state. The changes needed are minimal but impactful. Let's explore how to set this up. Step 1: Initialize State We'll start by setting up two pieces of state in our component — one for managing whether the dropdown is open and another for storing the current text of the button.

This function will accept the text of the currency as an argument.
