JS code :

const display = document.getElementById('display');
const buttons = document.querySelectorAll('.button');
let currentInput = '';

let operator = null;
let firstValue = null;
let resetNext = false;

buttons.forEach(button => {
button.addEventListener('click', () => {
const buttonValue = button.textContent;

    if (button.classList.contains('clear')) {
        clearCalculator();
        return;
    }

    if (resetNext) {
        currentInput = '';
        resetNext = false;
    }

    if (buttonValue >= '0' && buttonValue <= '9' || buttonValue === '.') {
        if (buttonValue === '.' && currentInput.includes('.')) {
            return; // Prevent multiple decimals
        }
        currentInput += buttonValue;
        display.textContent = currentInput;
    } else if (buttonValue === '=') {
        if (operator && firstValue !== null && currentInput !== '') {
            try {
                currentInput = calculateResult();
                display.textContent = currentInput;
                firstValue = null;
                operator = null;
            } catch (error) {
                display.textContent = 'Error';
