While on one hand, various new programming languages and technologies are getting into the limelight for making the different app development processes more efficient. Whereas, on the other hand, many existing web and app development technologies are disappearing from the graph.  

In a scenario like this, keeping yourself updated with what’s the most popular programming languages in USA is necessary for both the developers and businesses to build profitable solutions.

The other thing to keep in mind is the choice of selecting the best programming language for iOS App Development or Android Development.

Taking the same thought forward, here we have created a list of Top 12 Best Programming Languages for 2021. In this list, every new system-level programming language is included to keep you up-to-date with the emerging trends.

1. Java

When talking about the top programming languages to prefer in 2021, Java tops the programming languages list. The language was once the primary language for Android development. But with the advent of Kotlin, many apps have switched from Java to Kotlin for futuristic services. However, this has not made a major difference in its market popularity.

This one of the most popular programming languages is still considered by leading enterprise mobile application development companies and introduced into the software development plan both as a backend and frontend programming language due to its impressive features, like:-

Now that we’ve covered the latest programming languages used in the industry, it’s quite possible that you’re confused with which one to pick for your app project.

Let us help you pick the right and most useful programming languages.

How to Choose the Right Programming Language for Apps in 2021?

The decision of which programming language is best in 2021 what is the most popular programming language for your app project depends on three factors, namely:-

1. App purpose

The main reason why you want to develop an app is helpful in picking the right language.

For example, if you want to create your presence on the web, PHP is the right programming language to go with as it holds the title of being one among the best programming languages for mobile apps 2019. If you need a programming language for database management, SQL is helpful.  But, if you want to add AI features to your app, the Python programming language is a good option.

2. Language characteristics

Are you developing a native mobile app or investing in Cross-platform app development? Are you looking for an open-source or licensed option? What type of technologies and features are you planning to introduce to your app development process? What level of security do you want to add to your mobility solution? These questions will help you to understand the technical requirements of your business app solution and thus, select the best programming language for app development.

For example, suppose you want to build an app based on the Machine Learning concept. If you are looking for a programming language with years of existence, Python is the right choice, for it is among the most useful programming languages. But, if you are ready to go with a newcomer based on the options it avails, TypeScript is apt for you.

Likewise, if you are planning to make your presence only in the Apple market, Swift is the preferred language for iOS development. But, when it comes to making an app for both iPhone and Android, going with JavaScript is a profitable deal, as it is deemed as a swift and versatile programming language by Github.

3. Local ecosystem

Last but not least, the decision of which top coding languages to prefer also depends on the skill set of your inhouse or hired developers. 

If you choose a programming language out of this most used programming languages list, you’ll experience a smooth app development experience. Your app project will face lower challenges and reach the market at the earliest.

But, on the flip side, the app development timeline might increase, hidden costs would more often be added to the overall app development cost and your app might fail to take the best advantages of the chosen language if they do not have a sound knowledge of the language you choose.
