Create a new array from array of objects [duplicate]

Question

I am learning javascript. I have an array that looks like :

myArray = [{
      "item":{
         "fields":{
            "myfield":"Value1"
         }
      }
   },
   {
      "item":{
         "fields":{
            "myfield":"Value2"
         }
      }
   }];

I want to create a new array with ["Value1","Value2"].

How should I do that ?

Thanks a lot !

Familiarize yourself with how to access and process nested objects, arrays or JSON and how to create objects and use the available static and instance methods of Object and Array. What can we expect the data to look like in general? — Sebastian Simon

You can use the Javascript function map() for this. :

const myArray = [{
      "item":{
         "fields":{
            "myfield":"Value1"
         }
      }
   },
   {
      "item":{
         "fields":{
            "myfield":"Value2"
         }
      }
   }];

const r = myArray.map(e => e.item.fields.myfield)
console.log(r)
