Over the last few years, the mobile app development industry has increased and multiplied exponentially, thereby, changing the way organisations or businesses used to operate across the world. Mobile technology has already taken over this digital era. And most people now reply on mobile devices for almost everything, for surfing the internet, connecting and communicating with their family and friends, for financial transactions, for shopping, and more. And on average, it is found the most of these mobile users spend 65 percent of their mobile time browsing different apps. And this remarkable use of mobile applications has made it essential for every business to have a mobile app today. The application development market has become beneficial for every business today and industry, right from startups to enterprises. And this has again increased the demand for app developers in Australia and all over the world. 
 
And there are over 600 different programming languages available ...
... now for building apps, each having its own set of pros and cons. With the changing business and consumer demands, and the advancements of technologies, new and improved programming languages are consistently getting introduced in the market. However, the choice of programming languages depends on the Operating System or platform for which the app has to be built and the business requirements. 
 
Well, the top 5 ones app developers must use in 2021 are discussed here in this article. Take a look. 
 
People invest a good amount of time in interacting with applications, which increased the need to go for mobile app development. And with this, the number and availability of programming languages also increased, out of which the best ones in 2021 are summarised here. 
 
JavaScript:
JavaScript is the most popular and widely used programming language now. It is a high-level and interpreted programming language, which can support functional as well as object-oriented programming. Also, it can be considered as a paradigm language that is run by browsers and can also be used for developing web pages. The JavaScript frameworks are well-versed for app development as well and you can use it for all platforms, iOS, Android, and Windows. Developers also love to work with JavaScript as it is pretty straightforward to use and is easy to control. javaScript also uses a UI mechanism that is quite similar to native Android or iOS apps. JavaScript is also used for building cross-platform apps for all platforms. It allows developers to reuse the native codes and help in building cross-platform apps faster, saving more time, effort, and coding heads. 
 
Kotlin:
Developers consider this language as the advanced version of the Java language. It is a versatile and interoperable programming language, which ensures to overrule all the shortcomings of Java. It is concise, clear, and has a very simple syntax. Kotlin is also easy to code. Also, it supports almost all the available IDEs. It can be also used with Java for creating more high-performing and efficient applications. It allows developers to write and maintain less codes, which also saves more time and effort. 
 
Objective-C:
The expandable version of the C programming language, Objective-C is an object-oriented, general-purpose language. A robust and updated option for developers, Objective-C is mainly used for building iOS applications. 
 
Though it is considered a little old with the introduction of so many new languages in the market, Objective-C is still in demand among the iOS application developers. 
 
Swift:
Swift is the most advanced and one of the latest programming languages designed for building apps for the iOS platform. Swift can be used for creating modern applications for different Apple devices like iPhones, tvOS, macOS, and iPads. It is a flexible language and comes with all the features that a modern iOS application must have. 
 
Python:
Python is a well-defined, object-oriented and high-level language used and favoured by mobile app developers. It is primarily used to create cross-platform apps that can run on both mobile devices and desktops on the web. Python is also easy to learn and understand, which makes it a favoured choice for the beginners in this field as well. Some of the most popular apps that are created with Python are Quora, Reddit, Spotify, Dropbox, Instagram, and YouTube. 
 
But now, with so many different programming languages available, how will you choose the right one for your project? For this, you need to first identify your requirements, determine the type of app you want, then streamline the possible and suitable choices from the list. It is also essential to scale the project to know the complexities of it before deciding the programming language for the project.
