My coding style is mostly influenced by good old personal preference, but also because of a certain internship where there was a lot of gain to be had by making everything as reusable and testable as possible.
I guess you could say my motto is usability, readability and flexibility:
I like tidy, reusable code with an emphasis on keeping code readable. I've always liked modular things I guess...
And I despise two things: curly brackets on the next line and spaces for indentation... But way worse is having no brackets at all (looking at you Python): it's clearer to have lower-level code inside some sort of "container" markers i.e. brackets (also gives more IDE functionality like color-coding hierarchically).
Indentation should always be tabs so anyone can have their own width of indentation set through their IDE, making it way more accessible to fellow colleagues!
And I also like having parameterized code over hard-coded functions: way more flexible.
