1. Scala

What is Scala?

Scala was created in 2003 and is becoming one of the most in-demand programming languages as it becomes a bigger part of today’s technologies. Scala is very much influenced by Java and has a lot of similarities, so there’s not much you can do in Java that you can't do in Scala.

Scala was created with the goal of being a better language than Java, avoiding the restrictive and tedious aspects of Java that cause frustration for developers. Learning Scala can be more difficult than initially learning Java, but the result is much cleaner and well organised code, which will ultimately increase productivity as it’s easier to use.

The Scala compiler is incredibly smart, avoiding the need for developers to state the obvious (which can be a frustration of Java). Scala relies on the Java Virtual Machine (JVM) and allows developers to make good use of standard JVM features and Java libraries. To the Java Virtual Machine, Scala code and Java code are indistinguishable.

You can code Scala in the same way that you code Java, so while you don’t need to know Java in order to become a Scala developer, it could give you a head start and should be fairly easy to transition to Scala from Java.

What is the average salary for a Scala developer?

According to ITJobsWatch the typical UK salary for Scala developers in 2020 is £74,000 per year. This has increased over the last few years, from £70,000 in 2019 and £69,000 in 2018. As you would expect, salaries in London are higher but excluding London the typical UK salary in 2020 is £55,000 per year.

The average UK salary for Software Developer jobs according to https://www.cwjobs.co.uk/salary-checker/average-software-developer-salary is £52,500 per year in 2020.

Why are Scala developers so well-paid? What is Scala used for?

Scala is a high-level general purpose language, and can be used for a wide range of applications, from machine-learning to web apps. Scala’s Java compatibility makes it well-suited to Android development, and it’s compatible with existing Java programs.

HMRC uses Scala for many government tax applications. Morgan Stanley uses Scala for their finance projects. Scala is also used for The Guardian’s website, and by certain teams in Apple Inc.

How many Scala jobs and developers are out there?

Scala is a well-paid programming language for a reason, and it’s likely to be around for a long time. Roughly speaking, there are around 880,000 Scala developers in the world, which was about 4-5% of the world’s software developers in 2018.

What is Python?

Python is one of the most popular programming languages in recent years and is a highly recommended language for beginners.

Why are Python developers so well-paid? What is Python used for?

It seems that while Python is an easy language to learn initially (and kids in school are now learning Python), there aren’t so many masters of it. If you’re exceptionally good at Python, you’ll earn a very good wage. So if you’re serious about a career in software development, Python is worth diving into and sticking with, especially if you can master it at a higher level than the majority of techies.

Python is used for developing desktop apps and web apps. Dropbox, Pinterest, Instagram and Reddit are amongst the apps built with it. Python is widely used for some of the most popular modern technologies, including machine learning/artificial intelligence (AI), robotics and Big Data.

How many Python jobs and developers are out there?

There are likely to be LOTS more Python developers around over the next decade as the youngsters learning Python will enter the jobs market too. But right now there’s plenty of room for skilled Python developers - there’s no signs of this language going away or dwindling in popularity anytime soon.
