Javascript值替换多个值

let x = 5;
x = 10; // 替换x的值为10

let x = 5;
let y = 10;
[x, y] = [y, x]; // 交换x和y的值

let person = { name: 'John', age: 25 };
person.age = 30; // 替换person对象的age属性值为30

let numbers = [1, 2, 3, 4, 5];
numbers.splice(2, 1, 6); // 替换数组中索引为2的元素值为6

let sentence = 'I love apples.';
let newSentence = sentence.replace('apples', 'oranges'); // 替换字符串中的'apples'为'oranges'
