reformat an object to another object format

Question

I have this object schema:

{
    car: [
      {
         //Object data
      }
    ],
    motorcycle: [
      {
         //Object data
      }
    ],
    ...
}

My question is how I get all the objects from cars and motorcycles in one object like this:

Basically I want all key,value pairs from motorcycle and cars in one object –

{
   key1 : {//Object Data},
   key2 : {//Object Data},
}

your expected output is not a valid object syntax. the syntax is key:value. You can have an array of object but not an object containing not naming list of object — jeremy-denis, Mar 16 '22 at 07:31
do you mean `{car:{//object data},motorcycle:{object data}}` — cmgchess, Mar 16 '22 at 07:32

`car` and `motorcycle` are arrays. Do they contain only one element? — jabaa, Mar 16 '22 at 07:35
Does this answer your question? [How can I access and process nested objects, arrays or JSON?](https://stackoverflow.com/questions/11922383/how-can-i-access-and-process-nested-objects-arrays-or-json) — jabaa, Mar 16 '22 at 07:37
Please try this: `const combinedObjects = {...origObj.car, ...origObj.motorcycle};`. — jsN00b, Mar 16 '22 at 07:38

A possible approach using Object.entries and map and Object.fromEntries assuming that there is 1 element in the key array of original object

const a = {
    car: [
      {
       data1: 'data car'
      }
    ],
    motorcycle: [
      {
        data2: 'data cycle'
      }
    ],
}

let x = Object.fromEntries(Object.entries(a).map(([key,[val]],index)=> [`key${index+1}`,val]))

console.log(x)

If more than 1 objects in key arrays can do something like this

const a = {
    car: [
      {
       data1: 'data car 1'
      },
      {
       data2: 'data car 2'
      }
    ],
    motorcycle: [
      {
        data3: 'data cycle 3'
      }
    ],
}

//Object.entries in case you want access to car,motorcycle....
let x = Object.fromEntries(Object.entries(a).flatMap(([key,val])=> val).map((e,index)=>[`key${index+1}`,e] ))

//this should work if no need to access car,motocycle..
// let x = Object.fromEntries(Object.values(a).flatMap((val)=> val).map((e,index)=>[`key${index+1}`,e] ))
 
console.log(x)

@jabaa bit hard to understand without giving a proper example tbh — cmgchess, Mar 16 '22 at 07:47
