how to merge data from different array to a combined array in json form.

 let NAME: any[] =[]
  let TYPE: any[] = []
  let OBJ: any[] =[]


  for (var i=0;i<getdata.length;i  )
  {
    var p =getdata[i].name;    
    **var a =NAME.push(p);**     // pushing data to Name

    for (var j in getTypes[i])
    {
    if (getdata[i].name ==getTypes[i][j].data.name) // get type is having req. data here
      {

        var k = getTypes[i][j].name ;
        **var s =TYPE.push(k);** //pushing data to type

      }
    }
      for (var j in getobj[i])
    {
      if (getdata[i].name ==getobj[i][j].library.name)         
      {
        var o = getobj[i][j].name ;
        **var g = OBJ.push(o);** // pushing data to OBJ
      }
    }
  }     
 
  console.log(NAME);   // result getting :- ['A','B','C']
  console.log(TYPE);    // result getting :- ['A1','A2','B1','B2','C1','C2']
  console.log(OBJ);   // result getting :- ['AA1','AA2','BB1','BB2','CC1','CC2']
});

Data required like this :

{ id=1; NAME: A OBJ:'A1','A2' TYPE:'AA1','AA2' }

{ id=2; NAME: B OBJ:'B1','B2' TYPE:'BB1','BB2' }

{ id=C; NAME: C OBJ:'C1','C2' TYPE:'CC1','CC2' }

Assuming that getdata, getTypes and getobj match the following criteria:

1. getdata is an array of objects & each object has name as a prop
2. getobj is a 2-dimensional array such that getobj[i] matches with the data on getdata[i] and that each element in the inner-array constitutes of: library.name and name
3. getTypes is a 2-dimensional array such that getType[i] matches with the data on getdata[i] and that each element in the inner-array constitutes of: data.name and name.

the below solution is one potential way to achieve the desired results:

const desiredObjectArray = getdata.map((data, idx) => ({
    id: idx,
  NAME: data.name,
  OBJ: getobj[idx].filter(
    obj => obj.library.name === data.name
  ).map(objData => objData.name),
  TYPE: getTypes[idx].filter(
    typ => typ.data.name === data.name
  ).map(typData => typData.name)
}));

Explanation / Approach

• Use .map to iterate on getdata array.
• Populate the id and NAME directly
• For OBJ iterate over the array at getobj[idx], filter in only those elements where library.name matches the getdata[idx].name, and then map the object to obtain just the name
• For TYPE iterate over the array at getTypes[idx], filter only those where data.name matches getdata[idx].name, and then map the object to return just the name

const NAME = ['A','B','C']
const OBJ = ['A1','A2','B1','B2','C1','C2']
const TYPE = ['AA1','AA2','BB1','BB2','CC1','CC2']

const result = []
NAME.forEach((item, index) => {
  const obj = []
  const type = []
  obj.push(obj[index], obj[index   1])
  type.push(type[index], type[index 1])
  result.push({
    id: index   1,
    NAME: item,
    OBJ: obj,
    TYPE: type
  })
})

return result
