There are many programming languages, however, which one is the best programming language for app development? The best programming languages for different types of projects are as follows:

The best programming languages for native Android app development

Both Java and Kotlin are great options for developing native Android mobile apps. They are fully compatible with the Android development toolkit.

1. Java

Java is one of the most popular programming languages for a long time. You can use it for many purposes, and it has been a mainstay of Android development for a long time.

This high-level and general-purpose programming language is excellent for object-oriented programming (OOP). Java is a class-based and compiled language. It’s a statically-typed programming language. You can run a Java app on any Java Virtual Machine (JVM) since Java is a cross-platform programming language.

James Gosling at Sun Microsystems had develop Java. The company first released Java in 1995. Java has seen many rounds of development, and enhancements to the language continue. Oracle now owns Java. Java is a free and open-source language, however, licensing requirements exist in some cases.

Java offers the following advantages for Android development:

  • The powerful features of the Java language work very well with the Android operating system. App developers can make optimal use of the features of Android mobile devices.
  • Java offers top-notch user experience, performance, and security for native apps running on Android devices.
  • Excellent documentation, tooling, and community support make it easy for programmers to write Android apps in Java.
  • Many developers already know Java.

2. Kotlin

Kotlin, a relatively new language is free and open-source. Google prefers it among the Android development languages. The Kotlin programming language is statically typed. It’s a general-purpose language. While it’s an object-oriented programming language, it also supports functional programming.

JetBrains, the creator of IntelliJ IDEA has created Kotlin. The company launched Kotlin in 2011, and Kotlin became an open-source project in 2012. There were many rounds of developments and enhancements since then.

Kotlin is fully interoperable with Java. It targets JVM. You can develop apps for Android, Windows, Linux, iOS, macOS, watchOS, etc. with Kotlin. Kotlin offers the following advantages for native Android mobile development:

The best programming language for front-end web development

JavaScript is the best language for developing the front-end of web apps. Along with HTML and CSS, JavaScript is one of the core underlying technologies of the World Wide Web.

JavaScript is a high-level programming language. This interpreted language is free and open-source. JavaScript is an object-oriented language, however, it supports multiple programming paradigms. It’s the scripting language for web pages. That said, you can use JavaScript for purposes other than web development too.

Brendon Eich created JavaScript at Netscape. The first release of the language was in 1995. Subsequently, many developers contributed to its growth. JavaScript is consistently one of the most popular languages. However, enhancements to it still continue.

JavaScript offers the following advantages for web development:

  • Simplicity;
  • Short learning curve;

  • Extensive documentation;
  • Excellent open-source tools created by a large community of JavaScript developers;
  • Community support.

A note about using JavaScript in developing progressive web apps and hybrid apps

Developers commonly use JavaScript to develop progressive web apps (PWAs). The similarities between progressive web apps and web apps make JavaScript a natural choice.

JavaScript has a key role in hybrid app development too. Several popular cross-platform mobile frameworks like React Native, Ionic, and PhoneGap are based on JavaScript.

The best programming languages for developing the back-end of web applications

You can use several prominent programming languages for back-end web development.

A note about Java, JavaScript, and Python for back-end web development

You can use multi-purpose languages like Java, JavaScript, and Python for back-end web development too. Spring, Struts, and Hibernate are highly popular Java frameworks for back-end development.

Node.js, a popular open-source runtime environment for JavaScript helps you with back-end web development. You can then use JavaScript for the entire web development project. Django is a popular Python framework for back-end web development.

1. Go

Go is also known as Golang. This open-source language is statically typed. Go is compiled, and it’s a strongly typed language.

1. I have a large iOS app written in Objective-C. Should I migrate it to Swift?

You can continue to have the Objective-C app. Apple will continue to support both Swift and Objective-C for the foreseeable future. While Swift is a more modern language, Objective-C was the mainstay for developing iOS apps earlier. It’s still the preferred language for many developers.

2. Can I use Java and Kotlin together while developing native Android apps?

You can use Java and Kotlin together in a native Android app development project. In a single project, you can call Kotlin code from Java code. You can call Java code from Kotlin code too. You can use Kotlin files in Java files. On the other hand, you can use Java files in Kotlin files too.

3. Which are the best frameworks to develop cross-platform apps?

React Native and Flutter are two of the best frameworks for developing cross-platform apps. While cross-platform mobile apps can’t fully match the user experience, performance, and security of native apps, React Native and Flutter come quite close.
