Software Development

8 Most Popular Software Development Technologies

By this time, it’s no secret that the tech industry is one of the fastest-growing industries globally. And you know what this means? It’s simple, it means more demand for skilled professionals everywhere. This, in turn, means more opportunities. So, no matter if you’re looking for jobs in Canada, Software Development jobs in the US, jobs in Europe, or remote jobs, you can be sure that there will be a demand for tech skills for some to come.

Here’s the thing, though. One of the biggest challenges in getting a job in tech is having the right skills. The problem is that the tech industry is ever-evolving with new programming languages, frameworks, technologies, and development tools being released constantly. As a result, to land your dream job you should not only learn and master these but also stay up to date as the industry changes.

But where do you start? Obviously, you can’t learn and master every programming language or technology there is. Because of this, we suggest that you focus on one or two and their related tools and technologies. So, what languages should you focus on? Luckily, we’re here to help and with this post, we’ll show you the most in-demand programming languages there are today. 

Ruby on Rails

During the early 2000s, Ruby on Rails was massively popular. In fact, shortly after it entered the development scene in 2005, it won the “Programming Language of the Year” award from Tiobe in 2006. One of the main reasons for this was that it gave developers a new approach to building web applications.

Although, since then, its popularity has decreased, it’s still one of the most popular programming languages out there. In fact, almost a million websites globally still use Ruby on Rails. Nowadays, it’s used for a variety of applications. One of its most common uses, as mentioned above, is for building web applications because it allows developers to develop faster which, in turn, saves companies time and money.

Because of its flexibility, cost-effectiveness, and its ability to handle high traffic, it’s also used for:

  • Social networking apps like Twitter 
  • eCommerce platforms like Shopify
  • Booking platforms like Airbnb
  • Streaming platforms like Hulu

ReactJS is a free and open-source JavaScript library that’s used to build user interfaces or UI components. One of the main advantages of using React is that it’s easy to read and makes it easier for developers to reuse code. As a result, developers can create web applications faster and easier. Also, other benefits are that it’s fast and that there’s a strong community behind it. 

Although many companies use ReactJS because it’s fast and it allows for quicker development, many companies also use it when they already have a team of JavaScript developers. Considering that JavaScript is the only front-end programming language and that most websites use it, it’s then easy to see why ReactJS is so popular. Actually, it’s used in over 2 million websites.

Some of the companies using React include:

  • Social media platforms like Facebook
  • Booking platforms like Uber and Airbnb
  • Streaming services like Netflix
  • Online mail clients like Microsoft Outlook
  • Cloud storage platforms like Dropbox

While ReactJS is one of the most popular front-end JavaScript frameworks, NodeJS is one of the most popular back-end frameworks. Actually a runtime environment based on Chrome’s V8 JavaScript engine, NodeJS offers developers an alternative to the traditional client/server model.

So, unlike the traditional model where the server responds to a client request and closes the connection afterward, NodeJS establishes a two-way connection. This capability promises faster performance and lower latency. Here, it promises an increase in application performance of about 50% with an accompanying decrease in response time and development costs.

Considering the above, it’s no wonder that at least 20 million websites use NodeJS. Some of its most popular users include:

  • Social media platforms like LinkedIn and Reddit
  • eCommerce platforms like Amazon and eBay
  • Streaming services like Netflix
  • Payment providers like PayPal.

Java is an object-oriented, all-purpose programming language that’s been available to the public since 1995. Because its object-oriented nature allows developers to write and reuse code for a wide range of applications, it makes them more productive and speeds up application development.

Another benefit of Java is that it’s platform-independent. As a result, developers can write code that runs on different machines and operating systems without specifically having to develop different applications for different environments. Also, it has a wide range of development tools and is relatively easy to use and learn.

Although Java has been popular for server-side web development and enterprise applications for years, it’s now also used for data science applications, machine learning, and mobile development. It also forms the basis of many big data technologies.

With that in mind, some companies using Java include:

  • Software development companies like Microsoft
  • Hardware manufacturers like Intel
  • Banking and financial institutions like Goldman Sachs and Citigroup
  • Various companies that develop Android apps.

Python was released in 1991 and from the beginning, its emphasis has been on readability. And that still stands today with Python not only being easy to read but also one of the best languages to learn.

And being easy to learn doesn’t mean it isn’t versatile. It’s, for instance, widely used for web development. According to W3Techs, it’s estimated that Python is used by about 1.4% of all websites. Considering that it makes it simple to set up web servers, it’s easy to see why.

Python’s trump card, though, is that it’s the language of choice for data science, machine learning, and AI. Here, it provides various libraries that can be used for data analysis, data manipulation, data visualization, and more. And when you consider that machine learning and AI will become more prevalent in the coming years, Python’s popularity is poised to grow even more.

Some of the companies using Python include:

  • Social media platforms like Facebook and Instagram
  • Streaming services like Netflix and Spotify
  • Cloud storage platforms like Dropbox.
  • Technology companies like Google.

When you consider that there are about 3.5 billion smartphone users globally and that there are more connected mobile devices in the world than there are people, it’s understandable why mobile development is so popular. Although you have different options, we’ll look at iOS first.

When it comes to iOS development, you’ll need to consider two programming languages. The first, objective C, forms the fundamental basis for iOS apps. As a result, when you want to pursue a career in iOS development you need a minimum amount of knowledge of Objective C. Unfortunately, it can be complicated and challenging to learn.

Because Objective C is slowly becoming obsolete, Apple has also released Swift. Although it shares much of the same concepts with Objective C, it’s far clearer and simpler. Also, because of its more modern features, it’s faster than Objective C, and developers can achieve the same functionality with less code.

When you consider that, as of the second quarter of 2020, there were 9.1 billion app downloads on the iOS App Store, it’s easy to see why there’s such a great demand for iOS developers. Some of the companies using Swift for iOS development include:

  • Ride-sharing platforms like Uber and Lyft
  • Trading platforms like Robinhood
  • Messaging platforms like Slack
  • Consulting companies like Accenture

Your other option for developing mobile apps is Android development. And here the numbers dwarf those of iOS apps. For example, as of the second quarter of 2020, there were 28.7 billion Android app downloads and 84.3 billion downloads for 2019 alone.

When it comes to Android development you also have a choice between two languages, Java and Kotlin. Although Java was the language of choice for developing applications on Android, Kotlin was made the official language for Android development in 2017.

One of the main benefits of Kotlin is that it allows developers to not only write more readable code but also that they require less code. As a result, this speeds up the development process and results in fewer bugs. In addition, adopting Kotlin is easy and it’s fully compatible with Java.

Some of the companies using Kotlin for Android development include:

  • Booking platforms like Trivago and Agoda
  • Messaging platforms like Slack
  • Education platforms like Udemy
  • Other platforms like Tinder, Mastercard, Intuit, and Zendesk

Although PHP is one of the oldest programming languages and it’s become less popular in recent years, it still powers an estimated 79% of the world’s websites. This is to a large extent because WordPress, the world’s most popular CMS solution, is based on PHP. Also, another popular CMS, Drupal, is written in PHP.

This means that there is a lot of legacy code that needs to be maintained. And for this PHP developers are necessary. Other reasons why it’s popular is its versatility, flexibility, speed, and that it’s easy to learn.

Some of the companies using PHP for their websites include:

  • Social media platforms like Facebook
  • Messaging platforms like Slack and WhatsApp
  • Corporations like Tesla and Mastercard.
