A Rule of Thumb: When to Learn New Languages When is the right time to learn new languages and is it good to learn multiple programming languages at once?
In my experience, all programmers should aim to know at least 3 programming languages. C is the preferred language for system programming. This general-purpose programming language is a good way to understand how computers work, from storing to retrieving information. As a foundational language, it helps to make learning other languages easier.
Java: For the past two decades, Java has held its position as one of the most popular coding languages. Almost every course in Computer Science will focus on Python. Many organizations are switching over to work in Python. For up-and-coming programmers who are unsure whether to learn Java or Python first, take a look at this infographic that displays the uses side-by-side.
Javascript: Javascript sits at the top of the list of the most widely-used languages. Both front-end and back-end developers utilize this language. Ruby: Ruby is an open-source programming language that continues to gain popularity. It is mainly used for website building. Unlike Python, which has just one solution for every problem, Ruby offers several approaches to a single problem.
Benefits of Knowing Various Languages As alluded to before, any programmer who wants to pave their path in the industry will need to be a polyglot programmer. There are a multitude of benefits to knowing more than one language, including: Flexibility: With more languages comes more flexibility. For example, if you want to be a freelancer, then your list of potential clients will expand in tandem with the languages you know. Since Objective-C is a language that extends C, you can also pick up a bit of C along the way.
Much in the same way Apple programming has evolved over the years, the world of Android programming has a newer language called Kotlin. It interfaces with Java, which is the core language for Android programming. You can build an Android app using both Kotlin and Java, so you should also learn a bit of Java. As you may already know, Java is everywhere! For quite a few years now, the idea of programming once and learning once these are different concepts, but both are still useful has been the holy grail of mobile app development.
As for programming on these platforms, you have a few languages you can choose to learn. Xamarin uses C , which is a very useful language in other ways, too. Another factor to consider when it comes to mobile app development is data. Mobile apps usually interact with one or more back-end systems. These systems are used for logging in users, storing their data so they can access it across devices, and providing other data services to the applications.
Plus, many mobile apps have their own databases on the device. There are multiple layers of a web app. Another layer is databases—this is where all the data is stored. The programming language for the web is JavaScript. There are several frameworks that use JavaScript to make it easier to build web apps, but they all rely on JavaScript.
All other aspects of web development are handled by interactions with a back end. The user interacts with the back end using URLs to fetch images, web pages, front-end code, media, and data used in the web app. There is a variety of languages you can learn to do back-end programming. One of the most popular web programming languages had been PHP. There have been databases built using nearly any language, but the tried and true language is SQL.
There are several flavors of SQL, and many databases allow you to use C or other languages to extend functionality. There are programming languages that are widely used in administrative tasks.
Python, for example, is used for all kinds of tasks involved in the deployment of apps, managing servers, and running just about any script to automate IT tasks. Shell scripting is another common form of programming that requires nothing more than just the command prompt or shell on your current computer.
Plus you can add filters to the output. Many tools have different ways to interface with them, including graphical user interface GUI and a command-line interface CLI. It also holds sizable market share in mobile games and application development using Android and enterprise web development world. You should learn Java to build robust, scalable server-side application. You can build projects of any complexity in Java, it has tools , technology, and community to help with.
It covers all essential concepts of Java in good details. Java is used by some of the biggest organizations e. Python is one of the most taught languages in school and colleges across the world. In the USA, Python has replaced Java from many academic courses as a preferred language to start with. What will you gain by learning Python? A lot. Python is one of that language which can be used as a scripting language as well as proper object-oriented language for a large project.
Many popular websites including Reddit are built upon Python frameworks like Django. In recent times, many large organizations are switching to the Python-based framework as well. Python is also increasingly used for new generation technology like machine learning , artificial intelligence, and data science. No wonder, because it has got some awesome machine learning libraries like TensorFlow , Scikit-Learn, and others.
I personally use Python for writing scripts though and it is very useful for doing something quickly e. Just write python scripts for ad-hoc tasks. Also, If you are confused between Java and Python to start with, take a look at this infographic , which compares Java with Python. In the last 5 years, JavaScript has totally dominated the world. It is no more a client-side scripting language, with the framework and libraries like Node JS , Angular , and React you can use JavaScript on Server side as well for user interface development.
