vue_es6对象合并 数组转对象

1、方法一：循环

const arr =  [{"name":"tableName","type":"string","xh":1},{"name":"fieldLenght","type":"int","xh":2}];
const obj= {};
arr.forEach(a => {
    const source = JSON.parse(`{"${a.name}":"${a.type}"}`);//利用JSON.parse将对象
    Object.assign(obj,source);                          //格式直接造出来
})
console.log(obj)





let result = {};
array.forEach((item, index) => result[item.name] = item);

2、方法二：析构函数

let result = {...array};
/* 
    {
        0:{"name":"Conan","age":17,"gender":true},
        1:{"name":"Ran","age":16},
        2:{"name":"Sherry","age":20}}
    }
*/

3、方法三：累加器

let result = arr.reduce((item, current) => {
    item[current.name] = current;
    return item;
}, {});
