Do people memorize the whole code?

Question

I have seen a few codes here. But , I am a little bit confused that people would write 500 lines , 1000 lines code? Or they copy them 🤔

Answer 1

It's possible to memorize the entire code of a project or program but most people don't.
Instead, you should get a solid understanding of the programming concepts and be able to reference documentation and other resources as needed.
Additionally, experienced programmers often use various tools and techniques to help them write and managed codes for example a text editor that has builtin auto complete and suggestions that makes memorizing the whole code less necessary

Memorizing won't take your far.
You need to understand the concepts no matter how long it takes for you to get it.
And all other things will come naturally.

Answer 3

That's the reason we write documentations. 😉

Answer 4

Thanks for that ☺️

Answer 5

Think of it this way: did the author of your favourite book memorize (or copy pasted) text? When you understand programming well, it is same as being fluent in native language. Programming -> communication (with computer). Programming language -> language used for communication (with computer).
If you think this way, you will understand that software expresses systems of (programmer's) thought just like scholarly works describe their author's thoughts. Both are systems of thought. One is used for communication between people. The other is used for communicating with the computer.
