When tackling your complex software projects how do you choose to represent your data? Do you simply pass around arrays of JavaScript objects of type any that you get from your API calls? Have you ever found yourself writing too much code and spending CPU cycles looping because your data doesn’t reflect the algorithms you’re using?

In this talk we’ll go back to some computer science basics to discuss some fundamental data structures you can use in TypeScript and how to get the most out of them. We’ll look at Records, Arrays, Stacks, Queues, Linked Lists, Trees, and Graphs. We’ll cover how to create these data types in TypeScript, how to use them, and when you might want to.
