If you’ve ever sat and stared at a monitor wondering, â€œWhat programming language should I learn today?â€, We may have an answer for you.
With so many different programming languages â€‹â€‹to choose from, it can be a little tedious trying to figure out which ones are worth your time. The short answer is all of them, as each language has its own use in one form or another. But for those who do not have unlimited time, it may be wiser to stick to the more popular options.
New programming languages â€‹â€‹are emerging all the time, but there are several tried and tested languages â€‹â€‹that have stood the test of obsolescence. It is these programming languages â€‹â€‹that are most in demand, stable and often provide employment opportunities.
As stated earlier, learning multiple programming languages â€‹â€‹can be beneficial, especially for programmers and senior developers, as it provides more tools for your professional toolbox.
Learning a few or all of the programming languages â€‹â€‹on our list should provide you with the in-demand knowledge needed for a high-paying job in development and programming.
What programming language should I learn?
We’ve compiled a list of 8 (and a few exceptions) of the most popular programming languages, serving as a cornerstone for anyone looking to get into programming and development.
Java is probably the most famous programming language in the whole world. Its goal was to develop server-side applications for mobile apps and video games that can be deployed in a cross-platform computing environment.
It is the foundation for Android app development, making it a must for anyone interested in Android app development. Not only that, but any budding programmer candidate will do well to make this programming language their religion.
It is also used in the development of web and desktop applications that will benefit from write-once and run in any programming language. The language is one of the easiest to learn and is in demand by employers around the world.
Where to learn it
There is plenty of free help for anyone interested in learning Java. The most popular course on this topic should be The Complete Java Masterclass by Udemy. This is one of the most comprehensive courses you can take to learn Java, and is suitable for both beginners and Java developers.
Python is considered the easiest programming language you can learn, but it is the best in web application design. Websites like Pinterest and Instagram owe their creation to Python, as well as a few others.
The language is one of the most in-demand programming languages â€‹â€‹today, and arguably the most important language you can learn in 2020, regardless of career path. It has already surpassed Java as the programming language most often taught in universities and academia.
Python supports multiple systems and platforms, can help increase programmer productivity, and is based on object-oriented programming (computer programs created by interacting objects or class-based instances). The average annual salary for anyone interested in machine learning, artificial intelligence and data science is around $ 112,000.
Where to learn it
Interested in learning Python? Python.org is a great place to start. If you don’t mind spending a few dollars, the Python Fundamentals course is also great for beginners.
C / C ++
Quite often, this is the first programming language you’ll ever learn if you were in college or took computer science classes in high school. Both C and C ++ are considered evergreen languages. Understand that if you ever plan to use any of these languages â€‹â€‹for employment, what was taught in high school is not enough to cut it down.
You can find many free C ++ courses online, ranging from beginner to intermediate. If you are just getting started with programming or are unsure of a career that you are willing to invest a lot of money in, learning C and C ++ is a great place to start.
After taking the time to learn C, you will find that this easy-to-learn programming language is actually the foundation for other higher-level programming languages. This should help you get to know more in-demand programming languages â€‹â€‹such as Java and Python much easier.
Where to learn it
Udemy offers many great courses to get you started with your C / C ++ education. Try C ++ Tutorial for Complete Beginners or C ++ Programming Basics, both of which are free.
Here we have another C language, C #. C # is one of the best programming languages â€‹â€‹for developing Microsoft applications. Anyone interested in developing a graphical user interface (GUI) for both the PC and the web will benefit from knowing this language.
Previous knowledge of Java will only benefit you in C # since they have similar syntax. C # is responsible for the .NET platform, and is also quite heavily used in game development for both PCs and consoles.
A key C # requirement today focuses on developing games using the Unity engine. If you’re planning to start developing your own video game, Unity is a good place to start. It’s free and generally easy to use, albeit a bit limited. C # is not as popular or as profitable in the job market as it once was, but it doesn’t hurt to add it to your programming language arsenal if the need arises.
Where to learn it
If your goal of learning C # is to become a part of Unity game development, the Complete C # Unity Developer 2D: Learn to Code Making Games course from Udemy is a great choice. For other uses of C # and Unity, you should sign up for Coursera’s Introduction to C # and Unity Programming.
Where to learn it
There is no better time to learn JS than in 2020, as it is now, like in the last decade, one of the most in-demand programming languages â€‹â€‹on the market.
Another language dominating the Internet, mostly in the form of dynamic, data-intensive websites and application development, is PHP. Some of PHP’s most significant advances can be found on sites like WordPress and Facebook.
PHP has been around for a very long time and is considered a programming language that you need to know. It is an open source language that is also considered to be quite slow in terms of web development compared to its counterparts.
Its open source code means that it is not a very secure programming language, but it is supported by a fairly large community of open source software developers. Learning PHP is minimal and can help you find employment (albeit shrinking) for web applications, content management systems, and e-commerce applications.
Where to learn it
Web developers interested in PHP will find a wealth of knowledge to share in the Coursera course, Building Web Applications in PHP. Do you want to create an e-commerce website? Visit the Learn E-Commerce PHP and MySQL from Scratch site found on Udemy.
This programming language was designed specifically for iOS applications. Back in 2010, Apple decided it didn’t want to force iOS developers to work with Objective-C, so Swift offers these developers an alternative language to work with. Anyone still using the Cocoa Touch libraries for interoperability can still use Objective-C as long as the structures they use remain unchanged.
Swift offers real-time output for interactivity and quick response to code or debug changes on the fly. The automated debugging system is actually one of the key elements of the Swift system, providing it with more interactive features common to scripting systems like Python.
The advantages of Swift over a language like Objective-C are that code is shorter (by almost a quarter), it is much easier to learn, and the developer community has more room to grow thanks to the quality of the applications it is more likely to create. Anyone hoping to get into iOS app development, or just looking to join the workforce using arguably the most lucrative programming language, will learn Swift well.
Where to learn it
Like most of the entries on our list, Udemy is a great source of knowledge for this programming language. Visit iOS 11 and Swift 4 – The Complete iOS App Development Tutorial to Become a Professional Newbie.
Just want to figure out what’s the matter? DZone.com has provided a great guide that will teach you a few things. To understand the basics of iOS 11, this course at pluralsight.com will get you started.
SQL & NoSQL
SQL has been around for a very long time. The purpose of SQL is the application backend database. As a separate language, SQL may not seem so useful. However, as a software developer, no matter which language you choose, you need to understand that both the database and SQL are necessary.
When it comes to querying data, accessibility and consistency, SQL provides. If you need to retrieve data from multiple tables in a database, SQL will quickly deliver that information. The entire language is optimized to work with a large number of table rows and to easily search the entire database for the project you are working on.
As powerful as SQL is, it has significant drawbacks, including the difficulty of converting data from objects to database tables, the availability of a single server, and whatever needs to be written, as opposed to an ORM that allows you to create auto-generated solutions. Although, to be honest, writing most of the SQL by hand tends to result in a tougher, higher performance query than an ORM. Anyone interested in a career in Data Science will excel at learning SQL.
NoSQL is gaining popularity due to its performance on low-cost hardware, the elasticity and scalability it offers over other types of available databases, and because no database model structuring is required. It has the potential to overtake SQL in the field of data science, but so far nothing is pointing to it as fact. Since it is a new language, it lacks community support (although it is expanding rapidly) and a standardized platform.
When you combine SQL and NoSQL, structured data, an integrated support system, and SQL schemas make it the preferred choice for enterprises, while NoSQL can find such rapid application development in its niche.
Where To Find It
In terms of SQL, Code Academy can help you get started with one of their courses. NoSQL enthusiasts can learn a lot from the edx.org courses Introducing NoSQL Data Processing Solutions and Amazon DynamoDB: Building Applications with NoSQL Databases.
Other useful programming languages â€‹â€‹to learn
Other useful programming languages â€‹â€‹for learning
As you look through the list, you may or may not notice some of the missed items that you suspected were present. It is mainly the Ruby language and its Ruby on Rails (RoR) framework as it is a language that is used in many web applications and is still in decent demand. It has been used by Shopify, Airbnb, Fiverr, Github, and Bloomberg, to name a few. While many companies still use it, it has lost a lot of hype over the past few years and therefore cannot be recommended as a subject to learn.
Other lesser-known programming languages â€‹â€‹such as R, Rust, Kotlin, and Golang are not currently popular enough to be worth knowing. However, we think Kotlin will benefit anyone who is serious about developing Android apps, as there are rumors that it could be the next big thing.
Golang, also known as Go, is quite difficult to learn, but anyone interested in framework development might find it worth the time. In the same vein as Go, you will find that Rust, which is also a very difficult language to learn, can be very useful.
It has the ability to create libraries that can link with other programming languages. If you’re interested, Rust for Undergrads should help get things off the ground.
