Find Node By Value Linked List In JavaScript - DevOutput

1. Overview

Finding a node by value in a linked list in JavaScript is relatively simple. All you need to do is create a basic internal structure, known as a ‘node’, which consists of two properties: element and next. The element property holds the data of the node while the next property points to the subsequent node in the list. To access the linked list, start at the head, which is a reference to the first node.

Then, while current is not NULL, check if the current value (current->key) matches that of what you are searching for. If it does, then you have found your node. Otherwise, keep traversing through the list until you find your desired value.

2. Benefits Of Creating Empty Linked List in JavaScript

Creating an empty linked list in JavaScript can be a great way to save time and reduce complexity when dealing with collections of data. Linked lists are a type of data structure that allows you to store data in a sequence of nodes, each containing a reference (or “link”) to the next node in the list. This structure makes it easy to add or remove items from the beginning or end of the list without reorganizing the entire data structure.

Additionally, linked lists are efficient at allocating memory since they only require as much space as necessary for their elements. Finally, linked lists have an advantage over other data structures in terms of iteration speed, since you can quickly traverse through all elements in the list. Overall, creating an empty linked list can help you save time and resources while effectively managing your data.

    const linkedList = new LinkedList();

    expect(linkedList.find({ value: 5 })).toBeNull();

    linkedList.append(1);
    expect(linkedList.find({ value: 1 })).toBeDefined();

    linkedList
      .append(2)
      .append(3);

    const node = linkedList.find({ value: 2 });

    expect(node.value).toBe(2);
    expect(linkedList.find({ value: 5 })).toBeNull();
  });

4. Conclusion

In conclusion, value linked lists in JavaScript are a great tool for storing and manipulating ordered data. They have the benefit of being able to store an arbitrary number of values while using minimal memory and allow for quick insertion and deletion of elements.

Furthermore, linked lists don’t require updating the index each time an element is added or removed from the list, which makes them ideal for situations when frequent modification is necessary.
