How to access the array of object response in typescript

Question

I am getting a response from an API, and this is the response when I viewed it using console.log(myArray).

I need to write the code in TypeScript Angular 6.

Output:Array(2)

 0:{ q1: 2
       q2:. 1
        __proto__: Object
     }
 1:{ q1: 2
       q2:. 1
      __proto__: Object
    }
 ___proto__: Array(0)
__proto__:object

Now I need to get the values of q1 and q2 in array. I tried but I am unable to do it.

How can I do that?

Answer 1

So, your Array has 2 elements in it.

1st is {q1: 2, q2:..}

the 2nd is {q1: 2, q2:..} also.

It looks like this: [{q1: 2, q2: ..}, {q1: 2, q2: ..}]

So you need the values of q1 and q2 out of array? Well, you have two copies of q1/q2 in your two separate objects. It's unclear whether they are the same.

If you just need the q1/q2 from the first object in your array, you can do the following:

let arr = [{q1: 2, q2: 3}, {q1: 2, q2: 3}]
arr[0].q1 // this is q1
arr[0].q2 // this is q2

If the q1/q2 values in each object are different, and you need all values of q1/q2, then you will need to loop through your array and get q1/q2 one by one. Like so:

let arr = [{q1: 2, q2: 3}, {q1: 2, q2: 3}]
arr.forEach(obj => console.log(obj.q1, obj.q2));

Answer 2

Here is your solution:

result = [];
getResult(myArray) {
  for(let i = 0;i < myArray.length;i++) {
    this.result.push(myArray[i]['q1']);
    this.result.push(myArray[i]['q2']);
   }
console.log(this.result);
return this.result;
}
