| I had a job for 2 years where I had the write the same program in both a dynamically typed language and a statically typed language around every week. On Monday morning, I wrote the dynamic typed version of the program. Then until Thursday afternoon wrote the statically typed version of the program. Then the rest of the week was writing tests that compare the output of both versions of the program. After 2 years of doing it, I think I would know. If that sounds weird to you, it's called Prototyping, shocking that someone might prototype something in a scripting language designed for prototyping, I know. The two classic examples are Eve Online with their "Python is our secret weapon". They used Python to out develop their competition. The other example is Discord who used Python to get to market quickly. Then they used Rust to reduce their operating costs by increasing the code's performance. Python adding type annotations is an unfortunate problem associated with too many people coming in from statically typed languages. The problem with success and all that. Statically typed Python codebases tend to be awful because the developers don't realise that they need to break the codebase down into smaller programs. JavaScript is not a very good language due to the way it was designed and built and pretty much anything is an improvement to it. |
