海外TECH	DEV Community	The Importance of Clean Code in Your Startup's Success	https://dev.to/chainguns/the-importance-of-clean-code-in-your-startups-success-ooc	The Importance of Clean Code in Your Startup x s SuccessClean Code has become a bit of a buzzword recently but it is important both as a developer and as an executive or CTO in a startup Investors want to see that your startup is run efficiently and that you have a good understanding of your code base If your code is clean it will be easier for them to understand what your startup does and how it works This can give them the confidence they need to invest in your company As a developer and from my own experience writing clean code especially in a startup where new ideas are tried every week keeping your code clean will help you when you inevetiablly have to go back and reduce your tech debt or just fix some things Customers want to know that their data is safe and that your product is reliable If they see that your code is wellorganized and easy to read they ll be more likely to trust your product Additionally if you have clean code it ll be easier for you to make changes and add features down the line Partners want to work with startups that are organized and have a good understanding of their technology If your startup has clean code it will be easier for potential partners to assess your technical capabilities and decide if working with you makes sense for their business clean code is crucial for the success of any startup By investing in clean code from the start you ll save yourself time and money in the long run while making your startup more attractive to potential investors customers and partners How to write clean codeThe first step to writing clean code is to keep it simple This means using clear and concise variable and function names It also means avoiding unnecessary complexity The goal is to make your code as easy to read and understand as possible The second tip is to avoid repeating yourself DRY This means not duplicating code unnecessarily Duplicated code is more difficult to maintain and can lead to errors If you need to use the same piece of code in multiple places create a function or class for it This will make your code more DRY and easier to maintain The third tip is to use comments to explain your code Comments are important for making your code readable and understandable They should be used sparingly however as too many comments can make your code hard to read Use comments to explain why you re doing something not what you re doing The importance of clean code in your startup s successStartups should aim to keep their cyclomatic complexity low as this will save them time and money in the long run There are a number of ways to do this such as using comments and clear variable names In addition startups should use coding conventions and style guides to ensure that their code is consistent and easy to read A personal tipNever assume someone will understand a clever solution not even yourself in a month from now always document your snippets with a few words like mention before and make good use of variable names even if they are a bit long I have too many variables in my own code that are forgotten like temp temp temp df temp nuke code base and more The importance of clean code in your startup s success cannot be understated Not only can unclean code lead to costly errors and bugs but it can also make your code more difficult to read and understand This can have a major impact on your startup s bottom line as developers will need to spend more time working on your code if it is not clean There are a number of different ways to measure code quality but one common metric is the cyclomatic complexity This measures the number of different paths that a piece of code can take The higher the cyclomatic complexity the more difficult it is to understand and maintain the code As a result startups should aim to keep their cyclomatic complexity low in order to save time and money There are a number of ways to achieve this goal For example startups can use comments and clear variable names to make their code more readable In addition they should use coding conventions and style guides to ensure that their code is consistent and easy to read By following these best practices startups can ensure that their code is clean and easy to maintain both now and in the future In conclusion Code should be well organized and easy to read Code should be modular so that it is easy to change or add new features Code should be well tested so that bugs are less likely to occur Code should be well documented so that others can understand it easily Code should be consistent so that it is easy to maintain Code should be free of any errors or warnings within reason Code should be performant so that it runs quickly and efficiently Code should be secure so that it is resistant to attack or exploitation If your startup s code is anything less than perfect you re doomed to fail Make sure your code is clean otherwise your startup is going down the drain Star our Github repo and join the discussion in our

海外TECH	DEV Community	Why We Force You to Learn Multiple Programming Languages	https://dev.to/bootdotdev/why-we-force-you-to-learn-multiple-programming-languages-5dmc	Why We Force You to Learn Multiple Programming LanguagesI ve been building Boot dev as a side project for the last couple of years and have recently had many new students ask the same question Why does your computer science curriculum require me to learn more than one programming language It seems that a good number of students join the platform with the opinion that they would rather fully master a single language than split their efforts While I plan to explain this better in the app itself moving forward I wanted to write get this blog post out to provide an in depth explanation of why we have you learn several languages over the course of our CS program First some background on Boot devSo that you can understand where I m coming from let me explain what Boot dev is and what its goals are as an educational platform Boot dev is a batteries included computer science curriculum in the browser We have some strong opinions about the best way to learn to code For example We teach computer science and software engineering concepts first Specific technologies are just a mechanism by which we teach the concepts We are fully hands onWe have guided courses and unguided projectsWe teach modern technologies and languagesWe have a linear curriculum so students don t have to worry about what they should be learning nextWe gamify the experience as much as possible to keep students motivated So why can t the whole curriculum be taught in a single language If you look at the full CS curriculum we have planned in our public roadmap on Github you ll see that it s basically impossible There are certain concepts that are so tightly coupled to specific technologies that it makes no sense to try to teach them all the same way Let s look at a few trivial examples It s hard to really teach databases without SQLIt s hard to teach functional programming without a purely functional languageIt s hard to teach OOP without an object oriented languageIt s hard to teach hardware interfaces without an assemblerIt s hard to teach typing without a strongly typed languageIt s hard to teach web without JavaScriptIt s hard to teach ML without PythonIn short we have competing goals We want to teach all the concepts using as few technologies as possibleWe want to teach all the concepts using technologies that teach the concept best So how many languages are you going to teach me Over the course of my traditional CS degree at university I used programming languages I think that s too many I don t want to teach languages for the sake of teaching them It s really an optimization problem where we want to introduce as few languages as possible while effectively teaching every concept we want to teach I m confident that the full curriculum for Boot dev will only require the use of about languages in total and that the majority of the program can just use JavaScript Python and Go Learning multiple languages removes your tunnel visionThere is an additional benefit to learning a few different programming languages that we haven t talked about yet By exposing you to different languages you will begin to see some of the benefits drawbacks similarities and differences between the various approaches to programming If you only ever write one programming language it s easy to assume a certain way of doing things is the best way the right way or maybe even the only way For example JavaScript and Go have wildly different approaches to error flow JavaScripttry doSomethingDangerous catch err console log err Goerr doSomethingDangerous if err nil fmt Println err By familiarizing you with several languages I firmly believe you will have a deeper understanding of each technology and when you might want to use different tools Will I be a jack of all trades master of none Personally I don t think so I really do think that if you were to focus on only a single programming language from the start of your learning journey up until your first coding job you would actually be in worse shape than if you d spent some time broadening your horizons Some people assume that learning to code is about learning a programming language They think that if you learn Python and then want to learn JavaScript you ll be starting over from That couldn t be further from the truth Learning your second programming language will take th of the time that it took to learn your first because of the concepts you learned will apply to both languages Once you ve used or different coding languages you can look at code in almost any language and understand what it says You might find yourself needing to look up syntax occasionally but everyone does that anyways Well could you at least reduce the number of general purpose languages If you ve browsed the curriculum you may have noticed that we ve settled on languages to teach the majority of the content JavaScriptPythonGoWe re going to try to use these languages for as much as we possibly can only mixing in other technologies as required by the subject matter For example using SQL when we re talking about relational databases Let me explain why we chose these three in particular Why JavaScript You can t really get away from JavaScript these days It s hard to learn about backend programming which is what most of our students are interested in without first understanding why a backend exists A backend only exists to power a front end so it makes sense that we would need to teach you a few front end basics first If you re going to build a front end on the web it almost certainly will use JavaScript so our hand is forced on this one Why Python Python gets out of your way syntactically speaking Algorithms and data structures are concepts that students often find more difficult to master so it made sense to us to choose a language that would allow our students to focus as much as possible on the logic Python also reads like English in many ways which again makes it easier to see what an algorithm in Python is doing at a glance Additionally we have AI and ML content towards the end of the curriculum so it s a two birds on stone situation where we can revisit Python at that point without our students needing to learn an additional language Why Go Our CS degree has an emphasis on backend programming and I ve personally had tremendous success with Go as a backend language Go will make it easier to teach things like concurrency compilers and distributed systems than some of the other choices I ve thought about I do think we might eventually have a Rust course that goes to an even lower level in terms of manual memory management but I haven t decided on that yet Questions Comments Concerns The best way to reach me directly is by joining the Boot dev Discord server You can also me on Twitter Let me know what you think of our approach	2022-07-31 14:10:36
