It's no secret that the world of mobile application development is lucrative and thriving for both iOS and Android operating systems. From budget planning to social media, apps are in abundance and yet remain in demand. And the best app developers make it look easy to get in on this industry.

But a high-quality mobile application isn't just the result of intelligent designers; there's also a swift and efficient programming language that brings all the elements together.

That's why if you're looking to break into app software development in 2021, you need to start by deciding which programming language to use.

In this guide, we'll walk you through our top picks of mobile operating systems that every aspiring mobile app developer should know, whether you're a total beginner or an experienced coder. We will also give you insight into the pros and cons of each, so you can make a fully educated decision on which language is best for your product.

What is a Programming Language?

Just in case you are completely new to this, let's briefly cover what a programming language is. Essentially, a programming language is used to develop other software programs, operating systems, and web applications through lines of code.

The easiest way to think of it is a list of instructions for the computer or smartphone to follow. It essentially tells the device what to do to present the information how it's meant to be seen.

The results vary. Just think of how many apps are out there and how each has its own distinct layout, features, etc. That's thanks to a unique code that puts all the moving parts in place in a coherent way.

Coding scripts differ enormously, which means different programming languages are required for every app. Read on to discover our top nine picks of programming languages in 2021 and what makes each different.

1. JavaScript

Even if you're brand new to developing Android applications, you will likely have heard of JavaScript. It is a programming language that has been used to develop numerous other online frameworks and web applications.

Part of its popularity is due to its efficiency and versatility. It allows you to fully develop both iOS and Android applications across multiple platforms, thanks to its unique React Native framework.

Pros

 Well-known due to its universal popularity Ideal for web apps and as a mobile app developer Ideal for beginners as a general-purpose programming language

Cons

• Lacks browser support

2. Swift

If iOS app development is more your speed, then Swift is the mobile app developer for you. While other mobile app developer languages may be suited for Android app development, Swift programming is the official choice for iOS. It is also easy to learn and navigate, so it's ideal if you are new to the world of software development.

Pros

• Largely self-contained, meaning you don't need to use additional external operating systems

• Swift programming is specifically designed to avoid bugs

• Requires minimal maintenance

Cons

 Designed for iOS app development exclusively, so cannot support multiple platforms

3. Java

Not to be confused with JavaScript, Java is an object-oriented programming language that can create applications that run on a virtual machine or browser. This differs from JavaScript, as the former can only run on a browser. It is an ideal programming language for Android app but can also be used for iOS app development.

Due to the popularity of Java, there is incredible potential for career growth as a web app developer associated with this program.

Pros

• Highly popular and can run on both virtual machines and browsers

• Applicable to both Android applications and iOS app development

Cons

• Runs slower than more modern mobile application development software

4. Scala

If you want to launch your mobile app developer aspirations with only the newest operating systems at your disposal, Scala should be top of your list. It possesses a distinctly reliable system that won't crash on your nor suffer from numerous bugging issues.

If you're looking for a modern, renovated version of Java, Scala could be it! But don't be so quick to ditch Java, as the two are actually compatible through Java's virtual machine.

Pros

 Reliable and bug-resistant, so you can focus on developing effective native apps Compatible with Java Modern and innovative design while remaining easy to learn

Cons

• It doesn't possess the same developer pool of more experienced operating systems because it's new

5. Kotlin

If you don't want to use Java, but you aren't quite ready for the newness of Scala, then Kotlin is the perfect compromise. It is widely considered a compromise between the two. It's an advanced version of Java while still maintaining the classic feel of the earlier software.

Kotlin's biggest strength is its clarity. It's easy to learn how to use Kotlin due to its concise and clear general-purpose programming language, ideal for both the new mobile app developer and the veteran coder alike.

Pros

 Clear interface improves the overall user experience

 Provides a balance of Java and Scala in one mobile application development software

 Supports almost every type of IDES

Cons

• Not quite as fast as Java

6. Python

The versatility of Python is how it earns its popularity. It can be utilized to create web apps across multiple platforms, including iOS and Android. You can even use Python to create desktop applications from the ground up, without the need for any external operating systems.

It is also easy to use, even for beginners, as its interface is clear and readable. It has its complexities, but they can serve as powerful learning curves to sharpen your skills.

Pros

 Easy to use while remaining a powerful software Fully versatile, able to develop web applications and across multiple platforms Used to develop several popular native apps, including Instagram, Reddit, and Venmo

Cons

 Consumes memory at a comparatively high rate, so it isn't an advisable option for those without a large capacity

7. PHP

If you intend to develop mobile applications that insist on database access, PHP is generally the advisable option. Of all the entries on this list, PHP is perhaps the easiest to learn, making it ideal for the beginner mobile app developer.

It has exceptionally fast loading speeds, even if your internet connection is letting you down. PHP was initially designed to build websites, but it is now fully capable of developing content-heavy web apps for iOS and Android.

Pros

 The perfect choice for a beginner

 Super-fast loading speeds, even if your internet is slow

 Multiple scripting and coding options available, including command-line and server-side

Cons

 Maybe too basic for advanced coders and programmers

8. C++

If you have no interest in developing web applications for browsers and your sole intention is to develop mobile apps, C++ was made for you. Like PHP, it is an ideal choice for beginners as it comes pre-loaded with multiple libraries that you can apply to your own app development.

Institutions use this software worldwide to develop operating systems for multiple platforms, including iOS and Android.

Pros

 Specifically designed to develop mobile apps

 Pre-loaded libraries to help beginners get started with their software development

 Possesses a positive reputation among numerous developers in industries such as game development and medical applications

Cons

 Not the greatest choice for web development

9. Object-C

Like Swift programming, Object-C is ideal for the mobile app developer that exclusively focuses on iOS app development. It is utilized by Apple app designers to create numerous effective programs. It is both an object-oriented programming language and a general-purpose programming language that is easy for beginners to grasp.

Though it is considered a little aged compared to Swift, it remains popular among numerous iOS developers.

Pros

• Specific focus on iOS app development

• Possesses a strong, positive reputation among Apple developers

• Compatible with C++

Cons

 Not for Android app
