Now that we’ve covered the top most popular programming languages used in industry, it’s quite possible that you’re confused with which programming language to use for your application.

Let’s us help you pick the right programming language.

How to Decide Which Programming Language to Consider in 2019-2020?

The decision of which programming language to choose majorly 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 language for mobile apps 2019. If you need a programming language for database management, SQL is helpful.  But, if you seek for a language to add AI features to your app, Python 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 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 the most active top programming language.

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 for making your app available only on iOS, choosing Swift is a good decision. But, when it comes to making an app for both iOS 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 what language to prefer also depends on what language your inhouse or hired developers know.

If you choose a programming language out of this Top 10 Programming languages list that they have expertise in, you’ll experience a smooth app development experience. Your app project will face lower challenges and reach to 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 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.

With the aforementioned factors and knowledge of the top 10 most popular programming languages for 2019-2020, we hope that you will find it easier to take the right decision and build a successful approach to enter the mobile market. But, in case you encounter any challenge, feel free to contact our tech experts.
