如何从数组中删除对象？

array = [{id:"1", name:"Jhon"},
         {id:"2", name:"Kabir"},

Answer 1

array = [{id:"1", name:"Jhon"},
         {id:"2", name:"Kabir"},
         {id:"3", name:"Rasel"}];
         
console.log(remove_by_id( array, '2' ));

function remove_by_id( array, id ) {
  const index = array.findIndex( el => el.id === id );
  if( index !== -1 )
    array.splice( index, 1 )
  
  return array;
}
