Please keep in mind that getting the "size" of an object like this is NOT a
constant time operation, as it would be with an array. If you are using
the size frequently you should consider keeping a separate variable with
the length yourself, instead of doing Object.keys(table).length every time.
You can iterate over the table with:
for (var key in table) {
console.log(key, table[key]);
}
