1 **Can’t pass the tests for remove methods even after copying the solution **

I coded this first myself but couldn’t pass the tests ,and after taking the hints or even pasting the official/FCC solution I am not able to pass the tests made for hashes remove method

  **Your code so far**

let called = 0;

let hash = string => {
called++;
var hashed = 0;
for (var i = 0; i < string.length; i++) {
  hashed += string.charCodeAt(i);
}
return hashed;
};

let HashTable = function() {
this.collection = {};
// Only change code below this line
this.add = (key, value) => {
  const hashedKey = hash(key);
  this.collection[hashedKey] = this.collection[hashedKey] || {};
  this.collection[hashedKey][key] = value;
}

this.lookup = (key) => {
  const hashedKey = hash(key);
  return this.collection[hashedKey][key];
}

this.remove = (key) => {
  const hashedKey = hash(key);
  delete this.collection[hashedKey][key];
  if (!!Object.keys(this.collection[hashedKey]).length)
    delete this.collection[hashedKey];
}
// Only change code above this line
};
