Introduction to Custom Data Structures

Explore the concept of custom data structures and understand how to modify or combine existing ones for efficient problem-solving in JavaScript. This lesson helps you identify when to use custom structures, implement them as classes, and apply them to real-world and coding interview scenarios to manage complex data efficiently.

About the pattern

Although many coding problems can be solved using existing data structures like arrays, linked lists, stacks, queues, trees, and hash tables, sometimes these structures may not perfectly fit the requirements of a given problem or may not provide the desired efficiency. This is where we need custom data structures. These structures can be implemented using basic data structures as building blocks and incorporate unique features or behaviors specific to the problem domain. In easier words, a custom data structure is the modified version of an existing data structure.

For example, we have to build a web crawler. It starts with a set of seed URLs, visits each page, finds ...
