✨ Crafting Better Code with TypeScript

TypeScript gives us incredible tools to write clean, scalable, and safe code. Here are three simple yet powerful principles to consider:

1️⃣ Use interfaces to structure types

   Interfaces are perfect for defining the shape of our data and creating clear contracts in our code.  

2️⃣ Use type aliases to express ideas more generally  

   Type aliases allow us to create unions, intersections, and more complex structures, giving flexibility to represent broader concepts.  

3️⃣ Use type predicates for specialty  

   Type predicates help us narrow down types safely and efficiently, making it easier to handle specific cases with confidence.  

By thoughtfully structuring types, leveraging type aliases for flexibility, and using predicates for precision, we can make our code cleaner, easier to maintain, and ready for growth.  

I’ve created sample code that applies these principles in the transactions domain. It demonstrates how to structure types, use type aliases, and apply type predicates effectively.
