Search Element in an Javascript Hash Table

We've kind of already implemented this in our put method. Let us look at it again in isolation.

Example

get(key) {
   let hashCode = hash(key);
   for(let i = 0; i < this.container[hashCode].length; i ++) {
      // Find the element in the chain
      if(this.container[hashCode][i].key === key) {
         return this.container[hashCode][i];
      }
   }
   return undefined;
}

You can test it using.

Example

let ht = new HashTable();

ht.put(10, 94);
ht.put(20, 72);
ht.put(30, 1);
ht.put(21, 6);
ht.put(15, 21);
ht.put(32, 34);

console.log(ht.get(20));
console.log(ht.get(21));
console.log(ht.get(55));
console.log(ht.get(32));

Output

This will give the output.

{ key: 20, value: 72 }
{ key: 21, value: 6 }
undefined
{ key: 32, value: 34 }
