Hypothetical Question:
Write a complex code to make it efficient Or
Write a simple code so that the next developer who works on it understands the code easily.

Write elegant code that is both easy to understand, and is optimized and efficient. They are not mutually exclusive.

Write code with documentation not with attitude 😌

Depends on what you're writing.
A trading platform needs to go for as efficient code as possible, no matter how ugly it looks.
A report builder needs to be more maintainable, and a tiny bit of extra processing time is worth it for the ease of changing a report later.

Keep it clear until you hit a bottleneck: Then optimise it if needs be.
But clear code can still be optimal. Don't assume that if it's easy to read that it's slow..

Write the simple code. Time it, profile it. Optimize if slow. Complexity can be worth it but i like to prove its worth it.

Usually i stop at "write the simple code" because when i dont and a bug appears, i have to write the simple code again anyway to figure out what i did wrong.

Comments might be nice.

Write efficient well document code. Then it won't be complex anymore!

@Fiftyseven welcome to devRant! Have your first ++. It is Very possible to write elegant, efficient code. Anything else is just being sloppy. 😉

First write clear and simple code. It's simpler to test it with unit tests.

Then optimize it till you can still read it.

If it is a must to be efficient more than readable and extensible, then write documentation. Really really good.

@iAmNaN Thanks bro! Long time lurker, figured it was time to start posting!
