how can i convert array of objects to one object-CodePudding

I want to convert object1 to object2 dynamically because keys like apple and water and inside objects are not static.

const object1 = {
        apple:[
            {a:''},
            {b:''}
        ],
        water:[
            {c:''},
            {d:''}
        ]
    }

convert to this form:

object2 = {
    apple:{a:'',b:''},
    water:{c:'',d:''}
}

CodePudding user response：

Use Object.entries to iterate the key value pairs, then use Object.assign to merge the inner objects, and finally collect the generated pairs back into one object with Object.fromEntries:

const object1 = {apple:[{a:''},{b:''}],water:[{c:''},{d:''}]}

const object2 = Object.fromEntries(
  Object.entries(object1).map(([key, arr]) =>
    [key, Object.assign({}, ...arr)]
  )
);

console.log(object2);

const object1 = {
        apple:[
            {a:''},
            {b:''}
        ],
        water:[
            {c:''},
            {d:''}
        ]
}

let object={}
Object.keys(object1).forEach((item)=>{
 let obj={};
 object1[item].map((e)=>{
    obj={...obj,...e};
 });
 object[item]=obj; 
})

console.log(object)
