How Do I Implement A Percentage Function In JavaScript Calculator? - Next LVL Programming

How Do I Implement A Percentage Function In JavaScript Calculator? In this video, we will guide you through the process of adding a percentage function to your JavaScript calculator. You will learn how to define a function that takes two inputs: a base number and a percentage value. We will walk you through the calculation process, showing you how to multiply the base number by the percentage and divide by one hundred to determine the correct percentage.

Validating user input is essential, and we will demonstrate how to check if the inputs are valid numbers using the "isNaN" function. You’ll also discover how to round the result for better readability using the "toFixed" method. Displaying the result in your calculator interface is another key aspect we will cover, ensuring users can see their calculations in real-time.

Additionally, we will introduce a reset function that clears the input fields and results, making it easy for users to perform multiple calculations. This project not only helps you practice your JavaScript skills but also creates a practical tool that can assist others in understanding percentages.
