07-HashCollisionLinearProbing.js

[chung2014]

In line 49, you are checking for a position that contains an element, so I guess you would like to break the while loop if there is no value for that position
so

while (table[index] === undefined || table[index].key !== key)

should be

while (table[index] !== undefined || table[index].key !== key)

[dear-lizhihua]

hashLinearProbing.remove('Jamie');
console.log(hashLinearProbing.get('Jamie'));

table[index].key will error

so

while (table[index] === undefined || table[index].key !== key){
    index++;
}
if (table[index].key === key) {
    return table[index].value;
}

maybe should be

while (table[index] !== undefined && (table[index] && table[index].key !== key)){
  index++;
}
if ((table[index] && table[index].key === key)) {
  return table[index].value;
}
