js 浅拷贝 子数组问题

[vicksiyi]

let original = {
    key1: '',
    key2: '',
    key3: [],
    key4: ''
}

let dist = Object.assign({}, original);
dist.key3.push(123);
console.log(dist);
console.log(original);
// { key1: '', key2: '', key3: [ 123 ], key4: '' }
// { key1: '', key2: '', key3: [ 123 ], key4: '' }

解决方案：
JSON.parse(JSON.stringify(original))
