Can a programming master remember the code and type it out without using Baidu?

A novice who is new to programming asked a question on Zhihu:

想知道那些编程大佬是不是代码都能记住，然后不用查百度就能啪啪啪打出来呢？
从大一接触编程到现在一直在练习代码，但是很多函数和库还是没有办法记住，要用到还是得查百度，不知道是我太菜了，还是大家都一样。

The following is an excerpt of some wonderful answers from netizens:

You sit across from a programmer and listen.

If this guy is typing on the keyboard, he also smiles from time to time. Don’t be in a hurry to worship. Many times I might just be chatting with the girls from the testing team/art team/product team/operation and maintenance team.

If this guy's keyboard is regular and spaced, click... click... click, and his face is calm. Then it is possible that you are copying & pasting code.

If this guy frowns and looks around, he will type on the keyboard for a while, and then look around again. This is only possible when starting to program.

Those who are evaluated by keyboard typing speed are not programmers, but typists.

Netizens "discussed"

I am not a big shot. Can't remember, you know how many languages ​​I have to use now? Remember it all and don’t do anything else.

You see us typing code. If there were no reminder from ide, we might really just be typing on the keyboard or chatting with MM.

There is a type in software called: efficiency. Yes, efficiency. These are just jobs, done in the most efficient way of course.

Finally, a reminder: The hardest part about programming is not when you start writing it.

When I start writing, it means that my ideas, assumptions, theories, models, abnormal solutions...all already exist in my mind or in other tools.

If these preliminary preparations are not made, the loudest thing that the programmer will hit on the keyboard should be "backspace (return key)".

I have been working for so long. I have been programming for more than ten years. I have been exposed to no less than ten languages. I have done architecture, prototype design, and on-site development. I have involved no less than 30 projects, large and small. From the initial two-finger Zen The current Asymmetrical Six Finger Zen has not improved my typing speed at all, and it has not slowed down my output.

So, once it comes to typing the code, there is nothing difficult. The faster the process, the better. I can’t wait to let the machine generate it by itself. Why do you think template languages ​​have always been popular in large projects...

Microsoft's vs and jetbrain have begun to introduce intelligent predictive input, which is an insult to the program Member? Of course not, thank them for lowering your typist attributes.

Netizen "Little Panda Meow Meow Meow"

I have been using Google and Stackoverflow at work, and occasionallyQuora. Baidu and CSDN are not used, they are useless.

It’s not just me, the same goes for programmers around me with annual salaries of millions or even tens of millions.

As for why the questioner has this kind of trouble, it is because the questioner thinks that programming is just adjusting API, and is proficient in making things. He doesn’t know what advanced programmers do, and senior software engineers What are they doing?

Programmers have heavy responsibilities, either to develop important features, to solve a technical design problem, to ensure that services keep running in a specific environment, or to expand the underlying infrastructure, etc. , everyone is doing things that are highly abstract and rigorously implemented. As for whether API is familiar or not, there is no need to waste brain capacity.

No need to worry about these things. Of course, many scumbag companies like to test this kind of question during interviews, similar to how many ways Kong Yiji knows how to write a certain word.
