If you want to remove all occurrences of a given object (based on some condition) then use the javascript splice method inside a for the loop.

Since removing an object would affect the array length, make sure to decrement the counter one step, so that length check remains intact.

var objArr=[{Name:"Alex", Age:62},
  {Name:"Robert", Age:18},
  {Name:"Prince", Age:28},
  {Name:"Cesar", Age:38},
  {Name:"Sam", Age:42},
  {Name:"David", Age:52}
];

for(var i = 0;i < objArr.length; i ++)
{
  if(objArr[i].Age > 20)
  {
    objArr.splice(i, 1);
    i--;  //re-adjust the counter.
  }
}

The above code snippet removes all objects with age greater than 20.
