Top 3 Programming Languages to Learn in 2019

so most of these top three programming languages videos they always start off by saying it depends because blah blah blah I won't say that I'm just gonna give two so the top three programming languages depends where you're trying to optimize for Wow what a hypocrite anyways this video is sponsored by skill share so I've bucket it into three main categories or like main purposes for learning a new language and I think that encompasses most of you now I want you guys to be honest with yourself because I do think that 95% of you guys who say that you want to go into computer science because it is your passion you are lying to yourselves now that 95 percent they actually care about money the lifestyle or the promise that you'll be able to build a startup that will make you billions now that is totally fine because there's nothing wrong in choosing a career for its financial advantages that is called making informed life decisions but don't lie to yourself be honest because or else you might end up hating what you do but if you're honest with yourself you'll understand the trade-off that you made and you accept the setbacks and the negative outcomes of your life also don't feel bad that you suddenly realize they're lying to yourself I've lied to myself many times I lied to myself saying that I want to be a doctor when I was 13 because it was my passion to help other people get better but obviously as Asians we all know what the true reason we want to be doctors so that we can touch boobies right alright so now that you're honest for yourself put yourself in one of these three camps one I want to program because I want a tech job at a big tech company too I want to program because I want to build web apps fast so that I could make my own product or work for an early startup 3 I want to program so that I could be ahead when I start computer science next year as a freshman I also make one assumption you haven't programmed that much or you are a beginner because I don't think most experienced programmers care about the top languages they know that most languages are kind of similar and what they care about is more about what frameworks or engineering domain they should focus on alright so depending on which camp you're in I'm going to give you the top three programming languages now I'm going to give those to you so that once you start learning stuff that's actually important like engineering domains or frameworks you don't need to relearn these languages so that at least you can get that out of the way for example imagine if your goal was to do machine learning or play with data and fit some models then I would say you should go with Python but learning Python has nothing to do with learning machine learning but it's just that once you get to machine learning most probably you will use the language Python because of the frameworks like pi torch and stuff like that alright so let's start with I want to program because I want a tech job at a big tech company now before we go into that I want to tell you how the recruiting process works at these big tech companies you have three stages right the first one is to get an interview and then the second stage is to pass the interview and then the third stage is to do well in your job aka not get fired ask yourself what is my limiting factor is it that I can't get the interviews or is it that I can't pass the interviews or is it that once I get the job I'm not doing very well and I don't like it so think of it as a funnel and understand what your limiting factor is and then work on that if your resume is not picked up by d interviewer then it doesn't matter how great of a software engineer you're because you're never gonna get to that bottom of the funnel you're never gonna get to start working then there's no chance for you to show off your awesome software engineering skills that's just how life is unfortunately so if your limiting factor is not being able to get interviews then that means you have to work on your resume and if you'll have to work on your resume it means you have to have work experience there but you can't have work experience if you've never gotten a job so the alternative is getting referrals and in combination having good personal projects for your resume however if your problem is that you can't pass the interviews then that means you just have to up your data structure and algorithm skills and that means Li coding especially for these big tech companies because that's what they test you on if your problem is that you can't do your job well once you get in there then most of the time it's not because there are technical abilities but it's more about your resourcefulness and how independent I am kind of skills alright so here's the top three languages for beginners who want to eventually get into a big tech company doing a tech job so number one Python number two Java and number three C++ these three languages are the best for big tech companies during coding interviews and that is what you should be optimizing for if you have to put time into one thing then I strongly recommend that thing to be leak coding many people have been able to get into jobs like Facebook or Google just by being good at solving these leak code questions even though some of them might not even know what git is or build files are crazy now for interviews I think using Python is your best bet because it is not typed you don't need to do memory management and there are a lot of shortcuts that make it easier for you to code during your interview and that is extremely important because each line of code if you save about one or two seconds that adds up to a lot and also you don't need to use your brain to think about the syntax or particular language stuff so that you have more time or more space in your brain to think about the actual problem itself Python is also really good because many of the web frameworks like Django and flask are in Python and these frameworks are really good for you to make personal projects and these projects will translate well into your resume to get interviews I put Java and C++ there because I guarantee you that a big tech company at least one part of their system is written in Java or C++ C++ is usually used for more complex systems when performance is really important Java less so but it's a great language to build applications like for example LinkedIn uses it to sigmah uses it Palantir uses it now yes I put Java and C++ below Python but they do have one thing over Python your curriculum at school is probably using Java or C++ most universities I don't think they will teach in Python because Python is not a great language to learn fundamentals like types or you know building and compiling and memory management you don't need that in Python so that's why they preferred not to teach those things in Python because python is an interpreted language if you don't understand what that means don't worry about it because eventually you will that's how we learn stuff we just hear we just hear a lot of things that gets repeated to us and over time we connect the dots and then we realize oh that's what I meant Python Java and C++ have tremendous support in lis code usually when they give you answers or solutions to the problems they give it to you in these three languages yeah so then I put C++ below Java because C++ is a very wordy language and that's gonna slow you down during interviews so that's why C++ is at third place all right so if your goal is to build stuff like build web applications and build them fast and have fun with them then I think the top three programming languages are JavaScript Java and Swift this might be a little bit controversial but I'll explain it later now if you're like you javascript is a trash language shut up stop recursion tating what you've read on the internet and have your own opinions for Christ's sakes before I explain why I chose these programming languages let me explain how web apps are built you have a front-end and then you have your business logic in your back-end and then you have storage for your data that is usually how web apps are formed to reiterate you have the front end that displays to your users and then you have the back end that decides what to display depending on your data that you have and then you also have storage to store your data for example if you're making online tic-tac-toe then the front-end you display the grid for the players to interact with and then the backend you have the logic of saying oh if that's the case he wins if that's the case she wins if that's the case that's a draw and then on the data storage side you store in memory or whatever the state of the game all right so now that you understand front-end and back-end of a web app let me explain to you why I think JavaScript is number one and also why I said that my list was a little bit controversial now I think my list is a little bit controversial because python is not in there python is extremely popular for building backends for web applications lamp stack was very popular back then laughs is Linux Apache my sequel and PHP and then PHP got replaced by Python over time and Python became very very popular so a lot of frameworks like Django and flask made a popular I actually use Django a lot back when I was in college I built a website called porn Dora but that's a story for another time so yes Python was really popular but then Google released their v8 engine and then also concurrently nodejs came along which is a runtime environment for JavaScript that caused a bunch of web frameworks for JavaScript to pop up for example express especially because these web frameworks were so new they were built with scale in mind older frameworks didn't anticipate the scale that we would be operating at so they're at a disadvantage compared to the newer sexier frameworks that optimizes on throughput and scalability because of their event-driven architecture capable of asynchronous IO so using nodejs as your back-end is extremely popular for pet projects or even startups now you know tinder uses nodejs for their back-end if you know what I mean knob I'm serious they actually use node.js at what's great about JavaScript is that it's also good for front-end now you know websites its built in HTML CSS and JavaScript and then also front-end frameworks and libraries you have react and angularjs in addition even for mobile apps you now have react native where you can build iOS app and Android app by using JavaScript nodejs or I mean javascript is the only language that you can solely use to build a whole app and to end all right next I put Java and Swift the reason why I put Java and Swift is because for mobile development you need Java for Android and then you need Swift for iPhones so as you can see I never really talked about the specifics or the features of a language if you are watching this videos I highly doubt that you would care about the intricacies of a programming language what you should care is how much support you have on the internet for that language or purpose you're trying to accomplish for example C++ is a great language to build performing systems but if you want to do data stuff there isn't that much popular support for data frame style libraries so it's a crappy language if you want to do data stuff now on the other hand R is a great language for numerical computation but if you want to build web applications for it I don't think you have that much support because it's just not that popular to use art to build web applications I'm pretty sure someone made a web application framework but if there aren't that many people who use it then there isn't that much support for it and then every time you're gonna Google something you're not gonna find the answer so before you jump into a language and build a web app what you should do is that you should build a small project and then Google your way through your answers and then if you could see that Wow every time I google something I get an answer right away on Stack Overflow then it means this language has a lot of support and you should use it but if not then not so much and then once you find that that language is probably the best for your use case because you have the support of the whole internet all right now for the final bucket for you people who want to get ahead before starting computer science as a freshman from what I understand what I said before is that they usually use Java or C++ for their courses for me when I was in Waterloo the first programming language they taught us in was something called scheme which was a functional programming language and then later on they taught us using C not C++ C because they wanted to teach us memory management so that we understand the fundamentals of memory more and then later on we used C++ so that we learned about object-oriented programming and then depending on your electives you could usually use whatever you want whatever that gets the job done but mostly they make you use Java or C++ things that require high performance you usually want a language that you could compile into binary and then run it so for example C++ is a very popular choice for graphics and then C is a also very popular choice for low-level things so usually in OS classes or embedded systems classes you're going to be using C I personally like C++ more just because I think once you learn the language and the fundamentals of it it's pretty easy to port over other languages but that's just my opinion but anyways that's pretty much it thank you for listening peace out
