Does it fail? - A comparison of error handling in different languages

These are small examples to showcase how different languages handle errors. The goal is to find out how strict the language is in enforcing error handling. This is not meant to be a scientific in any way, shape or form. It is just me, experimenting with different languages.

The example

1. Create a program which reads it's local README.md file and prints it line by line.
2. See how the langugae enfoces you to handle possible errors.

How to run the examples

1. Install a container runtime like docker via Rancher Desktop (my favourite), podman or colima.
   1. If you want to use something other than docker, you will have to change the justfile to use your container runtime.
2. Install just.
3. Run just run <folder> to run the example in a container.

How to run the examples on your machine

• Take a look at the description in the README.md of the language you want to run.

Results

Language	Enforced error handling
Rust	✅
TypeScript (via Deno)	❌
Swift	✅

For a deeper explanation, look at the comments in the code.

Contributing

If you want to add a language, feel free to open a PR. Read one of the existing implementations for reference. You should use the best-practices of the language, but try to only use the standard library and keep it simple. Try to explain as much as possible in the comments but do not use field specific jargon. It sould be understandable for people who are not familiar with the language in which the example is written. Don't be afraid to PR your work in progress. I will be happy to help you.
