Removing an Element by id in JavaScript

Let the variable arr contain an array of objects:

javascriptlet arr = [
  {
    id: 'GYi9GauC4gBF1e2SixDvu',
    prop1: 'value11',
    prop2: 'value12',
    prop3: 'value13',
  },
  {
    id: 'IWSpfBPSV3SXgRF87uO74',
    prop1: 'value21',
    prop2: 'value22',
    prop3: 'value23',
  },
  {
    id: 'JAmjRlfQT8rLTm5tG2m1L',
    prop1: 'value31',
    prop2: 'value32',
    prop3: 'value33',
  },
];

Let the variable contain the id of the array element:

javascriptlet id = 'IWSpfBPSV3SXgRF87uO74';

Let's remove the element with this id. Let's use the filter method for this:

javascriptlet res = arr.filter(elem => {
  if (elem.id !== id) {
    return elem;
  }
});

The code can be simplified:

javascriptlet res = arr.filter(elem => elem.id !== id);
