How to Pass each value of an array as parameter to a get request call, and save all response in together in one json format [duplicate]

Question

How do i pass values from an array, as parameters to a get request REST api call and save all responses received, for each item per api request.

I have the following file format:

Const Data = [
  {
      user: '123456'
     
    },
   
  { 
      user: '123456',
    
    },
   
  {
      user: '123456',
     
    },
   

  }
]

the get url for the API is:

router.get(`/courses/:user)

What i'm trying to do:

pass all values of Data as parameter to the request, so it will look like this:

localhost:8000/courses/123456

This will happen for as many items in data, then gather together all the responses in on json output.

I have tried using forEach but no luck so far.

Expected result should be a Json data with all responses:

var output = [{response1},{response2}, {responds3}]

Call fetch() in a loop, saving the returned promises in an array. Then use Promise.all() to wait for all of them to finish, and make an array of the results. — Barmar

I'm trying to find a previous question that already answers this. I'm sure it's been asked many times. — Barmar

I can find lots of them that use jQuery, it's harder to find non-jQuery instances. Although the general idea should be the same, just replace $.ajax with fetch and $.when with Promise.all — Barmar

const Data = [
  {
      user: '123456'
     
    },
   
  { 
      user: '123456',
    
    },
   
  {
      user: '123456',
     
    },
  }
];

const result = await Promise.all(Data.map(({user}) => apiCall(user)));
