how to push all objects keys to a separate array in array using angular or javascript?

I have array of objects like this 

let array = [
 {'name' : 'Jack', 'age':23},
 {'name': 'Robin', 'age':25}
];

and I want an array like this 

[
 ['Jack',23],
 ['Robin',25]
]

I tried this code 

var myArr = []; 

var input = [
  {name : 'Jack', age : 23},
  {name : 'Robin', age : 25}
];

input.forEach((item,index)=>{
  for (var k in item) { 
    myArr.push(item[k]);
  }
})

But it is producing result like this 

["Jack", 23, "Robin", 25]

let array = [
 {'name' : 'Jack', 'age':23},
 {'name': 'Robin', 'age':25}
];

arrayOfValues = array.map(({name, age})=> ([name, age]))

console.log(arrayOfValues)

@HMR Thank you very much for sharing the valuable information.

The order in which you get the values in Object.values or Object.keys or for ... in or for ... of from an object (other than a Map) is not guaranteed and there is no specification in JS for the order.

Simply pass Object.values as callback to .map():

let array = [
 {'name' : 'Jack', 'age':23},
 {'name': 'Robin', 'age':25}
];

let result = array.map(Object.values);

console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }

This would be Array.map and Object.values like below

let array = [
 {'name' : 'Jack', 'age':23},
 {'name': 'Robin', 'age':25}
];

let res = array.map(d => Object.values(d))

console.log(res)
