如何从JavaScript中的数组中删除对象的属性？

Question

How to remove a key from an object

This function takes an array of user objects and deletes the moto key-value pair on each user object.

I have tried this code:

function deleteAllMoto(users) {

   for(var i=0; i<=users.length; i++) {

    delete users[i].password;
    return users[i];

}

Answer 1

Something like this:

function deleteAllMoto (arr) {
  arr.forEach(function(item) {
    delete item.moto
  })
  return arr
}

From your code you are deleting password not moto, then trying to return each user instead of the whole array after the mutations.

Answer 2

deleteAllMoto function should be

function deleteAllMoto(users) {

  for(var i=0; i<=users.length; i++) {
    delete users[i].moto;
  }
  return users;

}
