此⽅法在ES2015中ES2015 ，将⼀个或多个对象的所有可枚举的⾃⾝属性复制到另⼀个对象中。
Its primary u ca is to create a shallow copy of an object.
它的主要⽤例是创建对象的浅表副本。
const copied = Object.assign({}, original)
Being a shallow copy, values are cloned, and objects references are copied (not the objects themlves), so if you edit an object property in the original object, that’s modified also in the copied object, since the referenced inner object is the same:
作为浅表副本，将克隆值并复制对象引⽤(⽽不是对象本⾝)，因此，如果在原始对象中编辑对象属性，则在复制的对象中也将对其进⾏修改，因为引⽤的内部对象是相同的：
const original = {
name: 'Fiesta',
car: {teabag
color: 'blue'美国恐怖故事 第三季
}
}
const copied = Object.assign({}, original)
original.name = 'Focus'
lor = 'yellow'
copied.name //Fiesta
lor //yellow
