A Finite State Machine is a model of computation, i.e. a conceptual tool to design systems. It processes a sequence of inputs that changes the state of the system.
When all the input is processed, we observe the system's final state to determine whether the input sequence was
Functional Programming is a popular programming paradigm closely linked to computer science's mathematical foundations. While there is no strict definition of what constitutes a functional language, we consider them to be languages that use functions to transform data.
Python is not a functional programming language but it does incorporate
When we think about repeating a task, we usually think about the for and while loops. These constructs allow us to perform iteration over a list, collection, etc.
However, there's another form of repeating a task, in a slightly different manner. By calling a function within itself, to solve
Data structures organize storage in computers so that we can efficiently access and change data. Stacks and Queues are some of the earliest data structures defined in computer science.
Simple to learn and easy to implement, their uses are common and you'll most likely find yourself incorporating them in
Web APIs are the engines that power most of our applications today. For many years REST has been the dominant architecture for APIs, but in this article we will explore GraphQL.
With REST APIs, you generally create URLs for every object of data that's accessible. Let's say we're building
