3 Coding Techniques To God-Tier Developer 

Just like in real life people who can communicate good won't be just randomly spitting complex words that encapsulates bunch of meanings in itself, but will actually know when it is needed to use them, just like when you in a courtroom then maybe it might be a scenario for that or when writting an official document, otherwise, even tho you can say some badass words nobody will understand you, therefore failing to communicate, even tho what you saying makes sense.

Thats exactly what my lead keeps saying all the time. We have so much abstraction, that nobody can follow the code anymore. Debugging is so hard and take up too much time. You should not abstract for abstraction-sake.

As a novice programmer I find too little abstraction is way worse than too much. At my level (finance job vba and Python) people just out everything in one procedure. I think if you have little experience you should abstract until you release you’ve got too far, then dial it back, otherwise you will never know where the line is. Though I am coming from a consideration as programming as a skill all can use in their everyday job, rather than professional devs working on enterprise software.

you can fight the trend . kinda ugly people teach abstraction

​@@edmel144 Yes, you can do both too much and too little abstraction. Beginners typically do almost no abstraction and mid devs are sometimes more prone to do too much. It is a bit like the old saying that if you just got yourself a nice hammer, everything starts to look like nails. Later you realize there are more tools that matter than the hammer. I'm not sure I agree on taking the abstraction too far and then try to reverse it though. It is easier to abstract and split functions apart than going the other way, I would say. Once you have created too many small functions and they are used everywhere in the code, you cannot just remove them without having to refactor a lot of existing code.

People are in love with abstractions man. They just abstract anything and everything.

Thank you! So refreshing to hear this from others.

Yeah also realized these having 10 enterprise projects. Abstractions are good in theory, but an overkill and overengineering if no one will actually used it and it is only specific to that context. There are only good to when you rearch the project. Scope and requirements of the project keep changing in the middle of the process.

Programming is about abstraction. This video is about how to manage abstraction. The results don't have a crazy amount of more "abstraction layers", you're being ridiculous. Also, pure functions are easier to reason about so that part is valid. The issue with the video are the examples: it's pointless to wrap db.saveFormatted(name) into its own function that does nothing but call the method with the parameter. Same for the formatName function, the function for that already exists and it's the strings.TrimSpace function so there's no reason to wrap it unless you really want to rename it for some reason (there are valid reasons for wrapping to rename). In other words, the formatAndSaveName function was actually already consistent with what the video is trying to say, imo. After the changes in the video, all calls to the original formatAndSaveName function have to be replaced with a call to formatName followed by a call to saveFormatted. But it'd be more sensible to just use the original unwrapped library/module functions that have already been tested. And if you do this is many places in the codebase, it's sensible to make a function that does both of them (with the delimiter passed as a parameter) which is what the formatAndSaveName function was (after dep injection). So in that sense, yes, there's redundant abstraction in these examples but nothing "crazy". But let's be more generous in our interpretation: the examples in the video are just that, examples. The principles that they try to convey are totally valid and useful. You just have to be mindful when to apply them.

As expected from someone who do not do unit testing.

RU-vid has a built in pause function. All you got to do is click on the screen. You’re welcome.

Or maybe the creator should avoid situations where a viewer has to pause the video every 5 seconds ​@@Dungeon_Synth_Enjoyer

@@Dungeon_Synth_Enjoyer​​⁠Some people have neurological issues with moving text. That's why, for example, CSS has directives supported by every browser, to reduce motion. Your proposal to pause every so often is naive, unhelpful, and rude. Please educate yourself about accessibility guidelines, ie how to consider people with a range of disabilities, before you write any client side code.

@@Dungeon_Synth_Enjoyer Sorry, that's not the point. While the animations are very entertaining and flashy, you lose focus on what is happening. Just taking out the old and replacing it from various directions is distracting. If an element is removed just to be re-inserted in another place, it is better to just have it move from where it started to where it needs to be. Pausing the video just freezes all the elements out of position. A better approach is a side-by-side or over-under comparison.

@@Dungeon_Synth_Enjoyer yeah that's rather dumb argument. i shouldn't have to pause every 5 secs and even miss the thing because final code stays for less than 1 sec on screen. Also pausing loses train of thought.

Thank you for this! It really helps 🙂

Sad to see this comment not getting upvotes it deserves. Content makers on RU-vid are notorious for coming up with sterile examples upon which they try proving a point and, incidentally, revealing that they don't really understand what they are doing.

Other than "DI/Injection", the rest should really just be called "Compartmentalization"

In what language you cannot mock a dB?

​@@privateagent my statement was not about some language, but about the DI-trick, where you move DB initialisation outside of some function. There, outside, you still have to create DB connection and if you like to test this "outside code", you cannot do it, because it creates DB connection and sometimes it is not applicable for unit tests. So you have to mock again, and mock again and it could happen infinitely. At the end of the day you just don't test all your code with DB, you keep it untested. Hope it makes more clear my idea.

@@AAntonovG Hey thanks for your comment, for my understanding could you maybe clarify why refactoring would be impossible? Also if having the initialisation code in the meson function (or some init function) is not the best approach since you sometimes can’t unit test it. What would be the correct way of handling this situation?

Its only a simple example for the video you know right?

@@LawZist If it is only an example then what is the meaning of title "God-Tier Developer"

@@kazmi401 by showing you a simple example to teach someone a new skill that will get him one step further to be a god tier developer, or maybe it is just sound good and get more traffic and likes because its sound better.

The name of saveFormatted is fine. The name saveFormatted implies that what is being saved is already formatted. It isn't named formatAndSave, or processAndSave, etc. The fact that it uses the past tense of Format (Fromatted) specifies in plain English that the function ... saves something that has been previously formatted . Now I would be a little more wordy in my function name to something that describes WHAT is being saved, such as saveFormattedFullName.

@@Tinker77 it quite literally saves anything string you pass it regardless of whether it has been formatted or not

@@edmunns8825, oh, thanks, dude! I was totally sure that it is "in" as "in something" 😅

But the video is about functions not methods or functional programming not object-oriented programming. So the video title should more be like "coding techniques for functional programming"

Hell no lol.

Hey! Thanks for the feedback. I encourage discussion even if people disagree with me! So it’s a good thing imo. Maybe we can change their minds 🙂

Better than implicitly passing around some global variables like in malloc.

same here

Couldn't he just put the formatted name into the original d.saveformated? Why even make a function out of it, if it just calls another function?

0:30 the behavior of called functions should not change, as you first complete utility functions and then utilize them. The caller should know specification and it be concrete. Otherwise it is an infinite monkey problem.

0:55 compiled program should either check for dependency, or dependencies should be baked into the program.

1:58 you still need to allocate those dependencies somewhere in the code. So db variable will still be present. And since the type of parameter is concrete/known and not any, it is not so much of an injection, but rather swapping the value. If you mean an interface, then yes, we can talk about dependencies. But then the concrete type underlying interface should conform to interface specification.

3:10 where is atomicity? Function should either format or save to the database.

3:53 ehm, let's make first function in the video non-deterministic and second deterministic?

Thank you! This is actually really helpful. I will keep this in mind for future videos.

What is DO? You mean DI right? Also, this is a statically typed language. Your comment needs more work to be useful. But thanks for watching 🙂

They can, but wrapping a function with another function call is really useful when implementation of the function itself changes. It's the same principle as virtual/abstract methods. What if you would like to call a function that should ONLY be called when you are on android, or another function taht should ONLY be called when you are on IOS? you would have to create if checks every time you call that function, when you can just wrap it around to act as an interface and have the function itself chose the required strategy to perform its action.

@@lunarthicclipse8219 yeah your example kinda fits with what I said on the last part where it wouldnt look unnecessary anymore if you want it to have certain reaches, and thats understandable enough

@baxstart9008 yah exactly, that is probably the only time it's ever useful lol.

Nope, hard to read the codes...

Thank you! And thanks for watching. As for your question, I can’t really explain it in a comment. It’s not like there’s one tool that produces a good video. I use many tools to try to make the videos as engaging as possible.

When did I say mocking was the goal? 😂

Every dev agreeing on anything would be wild 🤪

What do you mean by atomic? When I hear atomic I think of transactions like in a database or something.

I would like to know too. The transition effects are of much better quality than the 'morph transition' in Microsoft PowerPoint. I would like to know what software was used in these code transitions, moving only the necessary words.

You’re right, should have gave more time

Go

Only if you are following a functional programming style. In object-oriented programming, you don't pass in that much parameters.

🤣yeah maybe you are right about the animations being excessive. I will tone it down in the future. But anyways thanks for taking the time to give feedback that is actually helpful.

Yes.

Actually, it is different...

Hey thank you! Good points that are helpful. I will keep iterating

Thank you for watching!

😂

Will do!

The code had several functions and external dependencies that could change resulting in unintended changes to the output of the function. This is what is referred to as "tightly coupled code." He uses dependency injection to resolve this issue but I don't recommend using the DI pattern especially for external dependencies. It's usually better to wrap external dependencies than to pass them in.

@@ImperiumLibertas that's another

You’re correct. I can’t spell 🤷‍♂️

Can you elaborate?

@@kantancoding What do you need him to elaborate? His point is concise and clear. Imagine applying this for a hughe codebase; it instantly becomes unmaintainable as you now have, as a result, complexized your functions interfaces, created lots of helper functions and populated all your files with lots of imports. You have to strike a balance

Understood for me

🙂

You got me. I can’t spell 😂
