I have an array of Objects

[{"a":{"name":"abc","age":2}},
{"b":{"name":"xyz","age":3}},
{"c":{"name":"pqr","age":4}}]

I need to convert this to

[{"name":"abc","age":2},
{"name":"xyz","age":3},
{"name":"pqr","age":4}]

Simply use map and Object.values

var output = arr.map( s => Object.values(s)[0] );

Demo

var arr = [{
    "a": {
      "name": "abc",
      "age": 2
    }
  },
  {
    "b": {
      "name": "xyz",
      "age": 3
    }
  },
  {
    "c": {
      "name": "pqr",
      "age": 4
    }
  }
];
var output = arr.map( s => Object.values(s)[0] );
console.log(output);

  const array = [{"a":{"name":"abc","age":2}},
  {"b":{"name":"xyz","age":3}},
  {"c":{"name":"pqr","age":4}}]

   array.map(item=>{
    return Object.keys(item).reduce((acc,key)=>{
      return item[key]
    },{})
  })

And straight ahead dumb way as well:

src=[{"a":{"name":"abc","age":2}},
    {"b":{"name":"xyz","age":3}},
    {"c":{"name":"pqr","age":4}}]

result=[]
for arr in src:
    for d in arr:
        result.append(arr[d])

You can use one of Array.prototype iteration methods, like map or reduce. I prefer reduce for such kind of problems. Array.prototype.reduce takes the second parameter as a default value, so it's an empty array and for every iteration that array is concatenated with the value of an object e.g. { a: { name: "abc", age: 2 } } will lead to adding { name: "abc", age: 2 } to the resulted array.

const input = [
      { a: { name: "abc", age: 2 } },
      { b: { name: "xyz", age: 3 } },
      { c: { name: "pqr", age: 4 } }
    ];

const output = input.reduce(
  (acc, entry) => acc.concat(Object.values(entry)),
  []
)

console.log(output)
