var a = {name: 'pardeep', 'sirname': 'jain'}
delete a['name']
console.log(a);

Just use delete keyword for the key like this -

delete objectName['keyName']

Answer 2

Use the delete operator

const deleteAttribute = (array, attribute) => array.map(x => {
  // Delete the attribute here
  delete x[attribute];
  return x;
});

const arr = [{
  attr: 'hello',
  color: 'red',
  organization: 'Good'
}, {
  attr: 'world',
  color: 'blue',
  organization: 'bad'
}];

console.log(deleteAttribute(arr, 'organization'));

Answer 3

You can use map and delete like below

var arr = [{
  name: 'hi',
  test: 'x',
  organization: 'X'
}, {
  name: 'guys',
  test: 'y',
  organization: 'Y'
}];

  console.log(arr.map(x => { delete x.organization; return x}));
