# Calculator App in ReactJS

Welcome to the Calculator App project for ReactJS! ⚛️

In this project, we'll create a simple calculator web application using ReactJS. Let's get started!

## Project Overview

### Objective

Create a ReactJS application that functions as a calculator.

### Features

- Display a calculator interface with numeric buttons and basic operations.
- Perform addition, subtraction, multiplication, and division operations.
- Display the result dynamically on the calculator screen.

## Project Structure

Create a new ReactJS project using your preferred setup (e.g., Create React App) and organize the components accordingly.

## Instructions

1. **Set Up React App:**
   - Create a new ReactJS app using a tool like Create React App.
   - Set up the project structure and create necessary components.

2. **Calculator Interface:**
   - Design a calculator interface with numeric buttons (0-9) and basic operation buttons (+, -, *, /).

3. **State Management:**
   - Manage the state of the calculator to keep track of the input and display the result.

4. **Implement Operations:**
   - Implement functions to perform addition, subtraction, multiplication, and division based on user input.

5. **Display Result:**
   - Dynamically display the input and result on the calculator screen.

6. **Run the App:**
   - Start the development server and open the app in a web browser.

## Example Code

### Calculator Component (Calculator.js)

```jsx
import React, { useState } from 'react';

const Calculator = () => {
  const [input, setInput] = useState('');
  const [result, setResult] = useState('');

  const handleButtonClick = (value) => {
    setInput((prevInput) => prevInput + value);
  };

  const handleClear = () => {
    setInput('');
    setResult('');
  };

  const handleCalculate = () => {
    try {
      setResult(eval(input).toString());
    } catch (error) {
      setResult('Error');
    }
  };

  return (
    <div>
      <div>
        <input type="text" value={input} readOnly />
      </div>
      <div>
        <button onClick={() => handleButtonClick('1')}>1</button>
        {/* Include buttons for 0-9 and other operations */}
        <button onClick={handleClear}>C</button>
        <button onClick={handleCalculate}>=</button>
      </div>
    </div>
  );
};

export default Calculator;
```

Remember to customize the calculator app, add features, or modify the structure as you see fit. Contributors can use this document as a guide to implementing the calculator app in ReactJS.
