While I love the idea behind Python's type hints, they are merely a shadow of the success of TypeScript.

Like the author, I've mostly given up on adding type hints in my Python code. I now only use them when I want to help my IDE find autocomplete suggestions.

Whereas TypeScript was a game changer for JavaScript. I used to hate JavaScript, but somehow TypeScript has become one of my favourite languages! How has the advent of Typing has changed my opinion on these two very similar languages?

- JavaScript without types is a mess, whereas Python comparatively was much better, esp since it does runtime duck type checks.

- Python type hints are much similar to Flow type hints in JS, which I tried, but ditched for the same reasons as Python type hints.

- I was hesitant to try TS's all in approach, cause it was harder to introduce into a project, but after having converted a number of projects to TS, I can see that going all-in is a much better approach than just adding hints as you go.

- TS does checks at many more levels. Eg, if a property is optional or could have different types, it is a syntax error if I don't check the value is valid before use.

- TS does an amazing job of auto-detecting types, so most of the time you don't need to specify types, and it enforces these just as if you declared them.

- TS has reached the critical mass were most popular packages now include type definitions, I very rarely have to add @types/* anymore. This means you get full intelisense on all 3rd packages! I spend a lot less time referring to documentation now!

In hindsight, compiling out types is a great work flow. TypeScript is so good that it has made me enjoy Python less. If there was ever a Python equivalent to TS which reached a critical mass of support, I'd jump all-in in a heartbeat.
