Hi, Is it possible find the same rid from array to array2 then push the wordspin values inside the array variable but i can’t use .find as it result to error.


let id1 = "recQoA4zwa0xZQVGL";

let id2 = "reckssVy1WsRtWPQs";

let id3 = "recSu7GQqd85dC5go";



let array2 = =

  {rid : id1, wordspin : "test1"},

  {rid : id2, wordspin : "test2"},

  {rid : id3, wordspin : "test3"},

  {rid : id1, wordspin : "test11"},

  {rid : id2, wordspin : "test22"},

  {rid : id3, wordspin : "test33"},

  {rid : id1, wordspin : "test111"},

  {rid : id2, wordspin : "test222"},

  {rid : id3, wordspin : "test333"}

]

let result = array2.forEach(function rid(r) {

    return function (o) {

        var ref = r.find(p => o.rid === p.rid);

        if (!ref) {

            r.push(o);

            return;

        }

        Object

            .keys(o)

            .filter(k => Array.isArray(o(k]))

            .forEach(k => o k].forEach(rid(refek] = refek] || |])));

    };

});

I want my result to look like this


"

  {rid:id1, 

  wordspin : "test1",

  wordspin2 : "test11",

  wordspin3 : "test111"

  }

  {rid:id2, 

  wordspin : "test2",

  wordspin2 : "test22",

  wordspin3 : "test222"

  }

  {rid:id3, 

  wordspin : "test3",

  wordspin2 : "test33",

  wordspin3 : "test333"

  }

]

Hi,


Yesterday I wrote a script to transpose vertical table to horizontal and stuck into object grouping task, which is similar to yours.

After your post I understood that I went wrong way, and how to solve my puzzle ))

So let’s help with yours.

besides grouping, you have other challenge - add new object properties according to those already existing. If wordspin2 property already exists, wordspin3 should be added and so on…

I belieive it has other easier solutions, maybe with spread+destruct, but I would use map array and transform to object.


const wsAdd=x=>x.map((val,ix)=>&'wordspin'+ix,val])

const wsObj=x=>Object.fromEntries(wsAdd(x))


group objects by Id is a standard task which have a lot of ways to do.

I took this reducer from net and changed a bit, to add just ‘wordspin’ properties and to get an ‘array of arrays’ on exit

const group=(arr,key,val)=>arr.reduce((res,el)=>((reslel&key]]=e...(resyel=key]]||s]),eleval]]),res),v])


now we need to connect these two ‘data processors’


const grouped = group(array2,'rid','wordspin')

const entries=(Object.entries(grouped));

const result=entries.flatMap(key=>({'rid':key=0],...wsObj(key[1])}))

output.inspect(result)

and here we go !

(if you need to correct numbers near ‘wordspin’ (start from 1 etc) - edit wsAdd function)
