exercise 5:
let b = users.filter(k => [k.id, k.email, k.ip_address] = ['deleted', 'deleted', 'deleted']);
console.log(b);

no need to reassign to a new array using map : users.map((user, index) => users[index] = 'deleted') (same version as forEach in this case)

ex 3 what about this is it work ?

&& ip_address.split('.')[0]<192 )

For excercise 5, i thought we have to keep the property name and replace its value with 'deleted', so i did this;
const usersArray = (users) =>
{
for(let i = 0; i < users.length; i++) {
users[i].id = "deleted"
users[i].email="deleted"

}
return users;
}

How would u recommend trying to set each individual user properties (id, email, ip) to "deleted"instead? I am guessing some sort of nested loop would work but wondering if there is more elegant solution.
