An Introduction to Typescript for Pythonistas | Issue #42

Published 8 months ago • 2 min read

Hi there,

​

If you’ve ever looked at TypeScript code and thought, “Hey, that kinda looks like Python!”, you’re not wrong. But under the hood, these two languages couldn’t be more different.

​

Python was designed for simplicity and readability. It’s dynamically typed, making development easy but deployment tricky.

​

TypeScript, on the other hand, adds strict static typing to JavaScript, helping with large-scale applications but making setup and debugging more complex. So, which one should you use? 🤔

​

In this week’s video, I break it all down:

✅ The key differences in typing, syntax, and philosophy

✅ When to choose TypeScript over Python (and vice versa)

✅ Some of the strangest quirks in JavaScript’s type system (yes, I talk about true + true === 2 😆)

​

If you’ve ever been curious about how Python and TypeScript compare, this is the video for you!

​

Cheers,

Arjan

Hi there, Have you ever found yourself writing functions like this? def render_article(article_id, db, logger, user, config, feature_flags, etc): …and then passing the same parameters through five different layers of your app? In my latest video, I walk through a realistic Python example and show how to fix this mess using the Context Object Pattern. I’ll start with the "before" version, refactor step by step, and explore: How to group related dependencies using a context object When this...

Hi there, This week’s video is all about uv workspaces, and why they’ve completely changed the way I manage Python projects. In the video, I walk you through a real-world example: I build a CLI tool and a FastAPI API that both fetch and summarize news headlines using OpenAI. But the real lesson is in how the project is structured. I show you how to share a local package between apps, define common dependencies like openai or httpx only once. And you can manage everything using uv’s workspace...

Hi there, When I see an if-statement with multiple elifs in my code, it almost always triggers an investigation. Is there some way to rewrite this to make the logic simpler? Is there a chance that in the future I'll need to add even more complexity? If so, I'll try to redesign the code so that I don't need that chain of if-elif statements. In this week’s video, I cover a design pattern that helped me eliminate many of those chains from a project + at the same time made the code easier to...
