immutable的基础使用

fromJS:深层次转换，可以将所有的原生JS对象都转换为immutable对象

toJS:深层次转换 将immutable对象转换为原生JS对象
let state = immutable.fromJS({
name:"张三",
obj:{
username:"123",
password:456
},
arr:[1,2,3,4],
abc:[
{
goodsId:1,
goodsName:"123"
}
]
})
console.log(state);
console.log(state.toJS());

/*
const list = immutable.List([1,2,3,4]);

//增
let list1 = list.push(10);
console.log(list1);

//删 改
let list2 = list.splice(0,1);
console.log(list2);

//查

//将immutable对象List转换为JS数组 toArray只能转换一层
let arr = list.toArray();
console.log(arr);

 

const list = immutable.List([1,2,3,4]);
const list1 = immutable.List(["a","b","c"]);
//合并
const list2 = list.concat(list1);
console.log(list2);

/*
const map = immutable.Map({

console.log(map)
//将map对象转换为原生JS对象 单层次的转换

console.log(map) // Map{a:1,b:2}

console.log(map1)
