For a beginner, Java is an excellent way to learn the fundamentals of programming before taking off the training wheels and continuing in more flexible, less-syntactically-rigorous direction like Python or JavaScript.
Sticking to a language before moving on is a common goal. However, in reality you are going to transition as you find languages that better suit you or your organization's requirements. Start with Java , not because it is optimal for your end goals , but because it will teach you what you like and dislike about programming and because your instructor is more familiar with it. That will give you a valuable perspective and allow you to make a more informed decision later.
There are many ways to solve problems in different languages, but the "best" language pragmatically is the one that you feel most comfortable using. In that respect, programming is like woodworking- you want to let the tool do the work. If there is another language that is "better" objectively but more difficult or confusing to you, you will counteract the anticipated benefits by having to struggle to write code.
The only way to solve this problem while avoiding opinions and tastes is to objectively look at what you are trying to build. Thus the most efficient part of your question is your last sentence: you want to build medical software and medical mobile apps.
In that case, the answer is definitely Java, as is for all "real" software projects. Python is good for data science, in other words for statistics. Its other competitive advantage is that it is easy to learn for beginners, but that would be a bad reason to use it for a "real" software project. JavaScript is a mess you don't want to get into. The major reason why it's popular is that many people learn it first, because its very basic features are easy to learn, although they don't get you far, and because it used to have exclusivity on the web.
But in reality it will make your life a lot harder after a few weeks, without any benefit. I know I'll get criticisms for that, but I stand fully by this position. Since you're already taking a CS course which involves Java, I would recommend you to keep learning it. That's why colleges prefer it as go to language for teaching CS concepts.
On the other hand, JS, Python and other such languages are dynamic in nature and hence, easy to learn. But you can't learn certain concepts polymorphism, abstract classes, diamond problem etc using these languages. So it makes sense to stick with Java in your case. While I've seen many people recommend Java and I agree with them , I think you can learn both. But it depends on how much time you got.
I recommend you first learn Java. Then python will be easy to learn, and focus mainly on modules for graphs. The reason why I recommend to learn both is because python is much better and easier to code about statistical analysis. But again do this only if you have time to just learn them. If your project doesn't have anything to do with statistics and data analysis I'm pretty sure you do though , learn only java.
Also if you are wondering why I never mentioned JavaScript JS , it's because i really don't recommend it. JS is much harder to learn and requires a lot of lines of code to do simple things.
My advice to anyone learning to program is to not obsess on the language.. Same as learning human spoken languages - the more you learn, the more ways your mind can interpret a new problem set. Learning them at the same time isn't a big deal just like growing up in a bilingual home.
Your language and your software stack are guaranteed to change 3 times in your career. Don't assume you're going to choose the "right one". And you wont waste any time learning one you never wind up using. As a person who works on linux and OSX desktops, I have a personal bias against working for companies and software stacks that require C or Visual Studio. But this is not due to their technical merits, but instead the OS as a platform condusive to efficient CLI toolchains and container management.
If you're windows bound, pretty much everything is available to you through VMs and docker. Ideally you do at least SOME full stack development learning. This means you'll need javascript, and thus nodejs would be a good stack to learn. If you ultimately like gaming or 3D, you might need C and certainly python. I personally love Java and Android's Kotlin varient for it's very very well designed multi-threaded libraries. Python should be equally "open" to 3rd party library review and thus again how they solve complex problems , though a lot of times, I see python resorting to compiled C-libraries and thus the cost to crack open the code and or trace through the code becomes too burdensome to bother.
Since your instructor is using Java, i'd start with Java. Good luck! Although java seems to be a good fit for you. It is a cumbersome language to get started out. It will be far easier for you to learn Python and stick with it long term. This is due to the fact you will be easily able to google things for python and you will spend less time learning the language, and more time using it to do what you want.
Making mobile apps is easier with Java due to the fact that google does not directly support app building with python. If this is your biggest priority stick with Java. Javascript: This language is the best language to learn if you are making a website.
However, for easy of use you can do all the database access stuff with python. And send back the data to your website. Javascript is also another cumbersome language in my opinion. Each language has its use. If I were In your situation, I would choose the language that's easy to start with.
There is always trade off between them. If you want to make mobile app JavaScript is better. I suggest start the one you feel more close and learn all of them : You are quite young you have enough time for them.
It would be great if you first go with Java. It could give you complete understanding of programming concepts. Such as data types. Later you can move to Python , which is great for data processing and Machin learning stuff. They have nothing in common except the name Java. J2EE is the enterprise edition of Java and JavaScript is a web-based programming language without typing etc.
There are a lot of differences between them and they serve very different purposes. If you want to get into web development learn JS, if you want to get into e. Java EE is an Enterprise environment based on the Java language. Javascript is a language originally developed for use in web browsers. Javascript and Java are not the same language. Not even close. They share no history. All they have in common is the first four letters of there name.
They get sent to the user's browser, which is where the Javascript would execute. If you really only want to learn the one language and don't need the Enterprise features of Java EE then consider Node.
I've not used that myself, however. I'm new to development, and I've been studying JavaScript and Ruby concurrently, but I'm to a point now where I should really be focusing my effort into learning one language.
I'd like a solid foundation and understanding, so that I can move forward with confidence. Everywhere I go, I keep hearing that RoR is a dying breed.
However, I really have enjoyed Ruby and Rails Its approachable, fun, and readability is great. I just don't want to set myself up for failure by saddling myself in with a stack that will take me nowhere.
What is your opinion on the future of RoR and would it be foolish for me to invest too much time in learning it over others? Ruby on Rails is far from being dead. In fact, this is a very popular choice in early-stage startups, given how fast and easily it allows them to launch their product and iterate on it. Even at more mature companies, you'll still find a ton of opportunities. Not for internal tools or legacy codebases, but for actual production workloads: web apps, APIs, etc Some may tell you that Ruby doesn't scale, but is it really Ruby that doesn't scale, or the code they wrote?
Languages have trends. Sometimes, recruiters will try to take you one way or another to meet their own agenda. Don't always listen to what you hear. Long live Ruby! Long live Rails! RnR even uses quite an amount of Javascript.
I think that Ruby, and Rails, are design by improving on previous languages, and shifting the perspective from speed to readability and general developer friendliness. Opposed to that, Javascript did not have any design goals at all, and seems to be repeating the errors of all language designs that existed before. So my advice is to to learn RnR first, you get a head start, Javascript will just come along with it.
And you can distinct yourself from other people that claim web development knowledge because they have done one javascript tutorial I know I'm cheating by recommending both, but that's because I don't think you can go wrong either way.
Lua supports assignment to a list of variables. Destructuring assignment has been a proposed addition to ECMAScript the language standard behind Javascript for awhile. In Lua , you can overload operators. In Lua , you can manipulate environments with getfenv and setfenv in Lua 5. In JS , all functions are variadic. In Lua , functions must be explicitly declared as variadic. Foreach in JS loops over object properties. Foreach in Lua which use the keyword for loops over iterators and is more general.
These can be looped over with the for For regular Objects, one can implement their own iterator functions. This brings it much closer to Lua. Integer literals in JS can be in octal. Javascript is heavily used in webpages and web MVC frameworks like angular, as well as in web services running under nodeJS.
Javascript can also be found in NoSQL databases like mongo. Lua is a small scripting language that is very good for embedding in other applications. This is exemplified by it's use in the game industry.
A game can be written to use Lua extensions and users can then create additional content. Both languages can be used as general scripting languages to an extent, however, both have different focuses. NodeJs is heavily web focused. It can be extended through the npm package manager.
Javascript is a better language to learn if you want to do web stuff. If you're young and you want to learn to extend video games or you play Roblox, Lua is a good choice. If you want a general scripting language Lua could be a good choice, but it requires much more work to be useful compared to something like Python or Ruby.
I like Ruby, but haven't done much Python. Python is by far the most popular scripting language right now for general desktop scripting. I use Lua as a general scripting language because I think it's an elegant, fun language to write.
Because the Lua language is so small, it means the author you! I like the smaller Lua method because my solutions are only exactly as big as they need to be tiny , and I have much more control over how it works. Lua is one of the cross-platform programming languages which is a small scripting language for designing a web application that is embedded in other applications.
To run any Lua codes we need to install a Lua interpreter which then the codes are executable, where this interpreter also provides some libraries, and the installation process is very simple. There is no need to install JavaScript which is already installed in many browsers such as chrome also along with powerful consoles are built in this programming language. This scripting language which works well-embedded part of any host application which is powerful but it is small so that it usually can be run on microcontroller platforms.
JavaScript can run on both browser and server. It is also possible for Javascript to run a web browser with Node. Js and this is the only scripting language that can be used on both client and server sides. Lua also has a very simple and readable syntax which is modeled from Modula which make it easy to lean and suitable for beginners who are learning Lua programming language. In JavaScript, the syntax is very easy to learn and it is easier if we known C programming language as the syntax is kind of C-like syntax when you start using JavaScript.
