2019: Top 3 Languages every coder should know

Annalise Neal 13.02.2019

2019 is shaping up to be the biggest tech year yet with advancements in AI, Robotics and Data security at the forefront. With the upcoming technology developments it is paramount we do not forget the programming languages and algorithms that make up the building blocks of these advancements.

Developers still remain one of the most in-demand skill sets across the technology market. The question becomes then: what languages will put you the step ahead of the market and stay the most in demand amongst your peers?

First comes first - What makes a language easy to use? 

When considering this I ranked the languages below based on the following factors:
Versatility – how versatile was the code in terms of uses and applications
Ease of use – ability for beginners to learn and develop
Speed – in terms of learn, coding and deployment 

With that in mind without further ado below are the most sought after languages in the market for 2019: 

Created back in 1991 by Guido van Rossum, python is definitely not new in the world of programming. However,  it is in somewhat of a renaissance presently due to its adoption within AI, machine learning and data analytics. It has become a favourite amongst beginners and seasoned developers due to simplicity to learn and ever-growing demand. 

Python is one of the easiest languages for a beginner to learn due to its simplicity. It is also one of the few languages in the market that is white-case sensitive – meaning that unless indented correctly the user will encounter logic errors. This teaches beginner coders the importance of indentation that can be easily carried across to more complex languages, allowing easier interpretation. 

The simple syntax nature of Python means it is a general-purpose language which can be used for a large variety of solutions including statistical processing, game building, website development and business applications. 

JavaScript is undoubtedly the most popular language worldwide currently. Supposedly designed in 10 days, JavaScript is the programming language behind the most stylish websites and applications. As a language traditionally used for front-end web and mobile app development, JavaScript usage has now been resigned for back end web design as well. 

JavaScript gives coders the ability to create Web Apps, Server Backends as well as both Desktop and Mobile apps, making it a unique offering in the market due to huge scope. 

A summarised version of the most popular and widely used JavaScript frameworks include: 

React.Js: The most in demand tech stack React.Js powers some of social medias juggernauts including Facebook and Instagram apps. React.Js gives users the ability to develop scalable apps that can accommodate the varied and constantly changing requirements of today’s information rich world. 

Angular.Js: Launched in 2010 and powered by Google, Angular.Js is one of the leading powerhouse members of the JavaScript library. This open-source framework allows users a more refined approach to web development with less turnaround time – essentially the tool behind stable secure beautifully designed web pages and mobile apps. 

Vue.Js: One of the easier frameworks to wrap your head around, it is a spin of React.Js, Angular.Js and Knockout.Js. Vue.Js is an open source framework for building user interface and single-page applications. 

Node.Js: is a server side platform built on Google Chrome’s JavaScript Engine (V8) for the purpose of allowing easy building of fast and scalable network applications. It is an event-driven model that is efficient and lightweight, which is ideal for data-intensive real time applications that run across several devices.  

Third but definitely not last, Golang most commonly referred to as ‘Go’ was released twelve years ago by Google and is becoming popular due its variety of uses including web development, servers and statistical processing. Through using a Go compiler that interchanges Go into JavaScript allowing users to effectively become a JavaScript developer without ever touching JavaScript or having to learn a different language, for example TypeScript. 

One of Go’s biggest selling points is that it supports two features that allows concurrency (the ability to deal with lots of things at once): Goroutines and channels. Concurrency is essential for building software that can take full performance advantages of multiple cores or threads. 

Although quite new within the market it is quickly becoming the promising code of tomorrow. Its increase in popularity is due to the fact that is lightweight open source language best suited to today’s microservices architecture. Go is widely used by startups within Silicon Valley and most of fortune 500’s list including Dropbox, Facebook, Uber, eBay, Apple and of course Google. Closer to home Go is largely adopted across the financial services industry with deployment by Macquarie Bank and AMP. 

So how do you choose which is the best language to become an expert in? It really comes down ideally to what you see yourself specialising in and where you see your passion developing. Start with shortlisting the following three questions: 

  • What sort of work do you want to do? 
  • How much programming experience do you have? 
  • Where do you dream of working? 

The most important piece of advice I can give is to choose an area you are passionate about and learn code correlating to that whether that is web design and development, mobile application or statistical processing. Just choosing the most popular codes now is not a safe option for the future or your happiness within your career! 

There is no one clear cut choice or crystal ball from which to view what codes will be popular ten years from now – mixing up your skills to suit both front and back end needs will help you to best stand out amongst your market.
