JSconst log = (person) => { setTimeout(() => { console.log(person.name); }, 3000);};let person = { name: 1 };log(person);person = { name: 2 };log(person);person = { name: 3 };log(person);const log = (person) => { setTimeout(() => { console.log(person.name); }, 3000); }; let person = { name: 1 }; log(person); person = { name: 2 }; log(person); person = { name: 3 }; log(person); 输出的结果是: 1、2、3。这段代码里，在内存中创建了三个对象。
