Make a resultant array with comparing two arrays

Question

I have 2 arrays like

let arr1 = [
  {id:1, name:'hhj'},
  {id:12, name:'ghdgj'},
  {id:5, name:'gd'}
  ]

let arr2 = [
{id:1, addr:'fsfhg'},
{id:8,addr:'rgdh},
{id:5, name:'gd'}
]

I want a resultant array by comparing two arrays id like,

resultarr =[{id:1, name:'hhj'}
   {id:5, name:'gd'}]

let names=[hhj,gd]

I want this names in seperate array

Does this answer your question? How to compare arrays in JavaScript? — mighty_dev

Ok but the essence remains the same. This thread is more focused with your use-case. — mighty_dev

If you want to obtain the objects whose id is in both arrays, you could do this:

let result = array1.filter(el1 => array2.some(el2 => o1.id === el2.id));

You can use the Array.map function to return only the names of the elements of the resulting list like let names = array.map(elem => elem.name)

your expected result is incorrectresultarr =[{{id:1, name:'hhj'}}]

in the first object you must set property like

resultarr =[{foo: {id:1, name:'hhj'}}]
