如何识别一组数组输入中的输入值是否发生了更改

function arrayHash(arr) {
    return arr.reduce((acc, val) => acc + JSON.stringify(val), '');
}

let originalArray = [1, 2, 3];
let currentHash = arrayHash(originalArray);

// 检查变化
function hasChanged(newArray) {
    return arrayHash(newArray) !== currentHash;
}

console.log(hasChanged([1, 2, 3])); // false
console.log(hasChanged([1, 2, 4])); // true

function deepEqual(a, b) {
    if (a === b) return true;
    if (typeof a !== 'object' || typeof b !== 'object' || a === null || b === null) return false;
    let keysA = Object.keys(a), keysB = Object.keys(b);
    if (keysA.length !== keysB.length) return false;
    for (let key of keysA) {
        if (!keysB.includes(key) || !deepEqual(a[key], b[key])) return false;
    }
    return true;
}

let originalArray = [1, {a: 2}, 3];
let currentArray = [...originalArray];

// 检查变化
function hasChanged(newArray) {
    return !deepEqual(newArray, currentArray);
}

console.log(hasChanged([1, {a: 2}, 3])); // false
console.log(hasChanged([1, {a: 3}, 3])); // true

let originalArray = [1, 2, 3];
let currentRef = originalArray;

// 检查变化
function hasChanged(newArray) {
    return newArray !== currentRef;
}

console.log(hasChanged([1, 2, 3])); // false
console.log(hasChanged([1, 2, 4])); // true
