What to write as code examples?

Question

Programming

Previously, I did not notice this, but now I increasingly see the phrase "attach examples of your code" in vacancies. What is meant by this?
And what about those who do not have open-source projects?
In fact, I am constantly programming ... But it's either work - with appropriate restrictions, or learning new things - which are also just slightly distorted public materials ...
What to do with such a situation?
Maybe sketch your framework from scratch in a couple of weekends, or something else? Throw in ideas where you can deploy more functional or architectural beauties - do they want to see them?

Answer 1

I have not yet seen a company in which it would be impossible to take a piece of a working file as an example. It still doesn't apply without context.
Write a toy: clear, interesting, difficult enough.

Answer 2

Here you are programming in Dzhanga. Surely you come across some moments that you have to write and copy by hand from project to project. Take this code or this idea and make a standalone application for Junga. For example, there is sorl.thumbnail, it seems like an excellent library, at least it was. Then they got smart with backends and storages, added versatility, and now ~ 170 requests to the database are generated for ~ 30 previews. As soon as I saw it, I sawed it out of the project and wrote my own image resizing. True, to lay it out, you still need to make a lot of effort, I'm not ready yet. Well, either fix this logic there and offer a pull request, or just make your own fork with normal logic.
Or here's another thing.
Now MongoDB is popular. Junga has mptt for working with trees, but it works with relational databases. But for Monga, I have not yet seen such a library. Trees in Monga also have to be stored. While I use some custom solutions. I would be glad if there was a sane library.

I'm currently writing a wordle that runs as a service on the host, not as an applet in the browser. I write without a contract, on the table. I write in golang. I offer code golfing.
