Calculator App using React JS with Source Code
Our goal with this article is to introduce our readers to a fresh concept of learning on the go while producing with us, and as our first project, we’ve decided to make a React Calculator. With a terrific start like this, nothing could have been a better way to count the miles to travel.
|Project Name:||Calculator App using React JS|
|Language/s Used:||React JS|

Why a calculator ?
We chose to develop the calculator for some specific set of reasons, and most of them are mentioned and described in brief.
- Simplicity: A calculator is a simple device that you have probably seen, used, and mistreated. You’ve seen a wide range of calculators, and now you have the opportunity to design a basic virtual calculator that can perform all basic arithmetic operations including addition, subtraction, multiplication, and division. Because the procedure is so straightforward, it will be easy for both of us to describe and comprehend it.
- Abundance of interesting points: A calculator may appear to be a simple device, but if you want to make one for yourself, you’ll need to identify and create all of the various components, as well as identify and establish a mutual interactive platform and, last but not least, deal with all of the failures, crashes, and bugs.
- Cosmetic Challenge: If you have an eye for detail, developing and styling a calculator will be a good place to start. The calculator itself should not take up a lot of space, but it does have several buttons to accommodate, and you will also have to consider readability and overall User Experience as this is your first UI project.
