Summary

There we have it, real-world web examples using stacks. The important thing to note in both examples is that the majority of the logic as expected does not revolve around the data structure itself. It is a supplementary component, that greatly simplifies access and protects your data from unintentional code smells and bugs.

In this chapter, we covered the basics of why we need a specific stack data structure instead of in-built arrays, simplifying our code using the said data structure, and noted the applications of the data structure. This is just the exciting beginning, and there is a lot more to come.

In the next chapter, we will explore the queues data structure along the same lines and analyze some additional performance metrics to check whether it's worth the hassle to build and/or use custom data structures.
