Krishi Shivasangaran Published On April 8th, 2024 Tech Talks

Find out the best programming languages you must try in 2024, including their features and benefits to help you choose the right one for your mobile and web app development.

In web-development, 

Front-end programming languages build how your chat app looks, 

while Back-end programming languages build how your chat app works.

Both these languages must interact with each other to create a fully functional chat app. 

Throughout this article, I will brief you about the various coding languages used across different operating systems. The context intends to address you to a full-fledged insight so that you will be able to get a better understanding on which languages best fits your chat application. 

Front-End vs Back-End Programming Languages: What’s the Difference? 

Front-end languages are used to create everything that a user is able to see directly on his chat screen. It includes the structure, design, styles, images, buttons, colors of the chat app (client side components). These languages completely take care of the responsiveness and performance of the chat client, which your customers use to send messages back and forth.

Similarly, Back-end programming languages are used to build the server-side your chat app. This part is used to construct the business logic of the app and it cannot be directly accessed by the users. Authentication process, API routing, and Library creation are few examples of the operations that can be done using the back-end programming languages.

Best Front-End Coding Languages To Build An App

The front-end language you choose will largely impact the user experience and performance of your app. Every front-end language in software development has its own unique advantage. I’ve listed them out based on the platform they are used.

Best Programming Languages Used in Android App Development

The most popular languages used to build an android chat app are Java or Kotlin. These languages are used in the development toolkit containing SDKs, emulators, and debuggers.

These languages are used in the development toolkit containing SDKs, emulators, and debuggers.

These languages are also supported by Android’s Gradle build system which allows developers to add third-party libraries to their apps using a Gradle package directive. This makes sure that both Java and Kotlin are highly compatible with third-party components, making it easy to build apps with plug-and-play features.

Let’s take a deeper look at the Android Programming languages you can learn in 2024 to develop your app:

1. Java

Java is one of the most preferred languages of choice for building a chat app in android platforms. Here are a good number of reasons why developers choose this language to build their messaging, voice, and video chat apps. 

• Java is a general-purpose object-oriented programming language, meaning it can be used to create a wide range of apps, without any limitations.

• A Java Virtual Machine (JVM) running on the OS plays a major role in tuning the performance of the apps that use low latencies. This gives developers the opportunity to optimize the speed at which your users can send and receive messages.

• Java is highly portable. It can run on any system by means of a Java Virtual Machine (JVM). This makes the app development process highly scalable and saves huge development costs. 

• Since Java is object-oriented, you can build unique objects for each component of your instant messaging apps, which can flexibly interact with other pieces of codes inside your program.

2. Kotlin

Another “official” language to build any Android app is Kotlin. Here are the reasons why developers choose Kotlin for their chat app development:

• Kotlin has both object-oriented and functional programming features making it more viable for developing unique functional app components.

• Concise than Java, Kotlin is a statically typed language that performs checks at compile time. This minimizes the runtime errors which means, any issues with the code are fixed before they can be compiled so that when the app runs, the performance is optimally maintained.

• One major feature of Kotlin is its interoperability – the ability to call java functions while java can call kotlin functions. It can also be used as an alternative for Java.

• Kotlin is null-safe. It minimizes app crashes due to null pointer exceptions.

Best Programming Languages Used to Build an iOS App

When you plan on building a chat app for iOS, iPad OS, tvOS, macOS, watchOS, I recommend 2 native programming languages for developers: Objective-C and Swift. Here is the narrow down of the details of why you should opt these languages:

3. Objective-C 

Objective-C is a sophisticated object-oriented programming language used in major Apple platforms with a concept of code for real-time objects and frameworks. Below are the list of reasons why developers should try Objective-C for their chat apps.

• Objective-C is a general-purpose, object-oriented programming language used in the iOS platform to build apps with modular components and reusable codes.

• Adds automatic garbage collection, an object memory management system in development. The garbage collector within your program identifies the objects referred by other objects and destroys the unused residues.

• This language uses its syntax from the C program and object-oriented messaging application features from Small-talk, allowing you to build expressive chat features. These syntaxes appear to be easy to understand as in the natural language.

• In order to support the nested coding style, several legacy codes are included in this language.

4. Swift

Swift is a compact, easy-to-use, open-source programming language that’s evolving as the first choice of developers to build a chat app in iOS platforms.

There are several reasons why you must consider Swift to build your iOS chat app:

• Swift is a general-purpose programming language that is flexible with iOS frameworks like Cocoa and Cocoa Touch.

• The codes are simpler and faster than any other programming language. It includes features like inference, closures, memory management, stack overflow prevention and generics.

• Swift is a statically typed language, making it trustworthy to render an error-free chat app at runtime. It also has a native error handling functionality, where the compiler identifies code ambiguities instantly.

• Contains in-built memory management techniques that are easy to implement and require less maintenance. This makes building chat apps with large volumes of storage capacity more optimal.

5. JavaScript

Javascript is a lightweight, versatile, platform-independent language that is used to build apps with a dynamic backend and rich user interfaces at the frontend.

Let’s check out why developers use Javascript for their web application  development:

• JavaScript is a high-level language that is used for scripting the client-side of web pages.

• This is a reusable code – which allows programmers to focus more on creating rich user interfaces than writing codes from scratch.

• Offers the flexibility for developers to typically run apps in other environments and compile codes in a wide range of development languages.

• It supports dynamic typing where you can use a single function to handle a different number of objects at the runtime.

6. React

React is an easy-to-use programming language used to build desktop apps with highly flexible and modular UI components.

Need reasons to try React as your development language? Here is our list:

• The codes are reusable – which means programmers can make use of the pre-written codes, modify them and use it to build app functionalities. This increases productivity and reduces the time for development.

• React has plenty of open-source libraries which can be exploited by developers to build a react chat app with numerous functionalities.

• The portability of the language is an added advantage. It allows easy transition to a react native environment.

• Adapts the concept of ‘Virtual DOM’ which allows the app libraries to keep a UI prototype in memory and sync with a real DOM.

7. Angular

Next in the row is Angular, which is again one of the most popular languages used to build apps for web platforms. The reasons ahead

will support the above statement:

• Angular has pre-built UI components that can be directly used within your programs to create a rich look and feel of your app.

• The TypeScript feature of this language allows developers to build chat apps with a clean and readable code.

• Highly preferred to create lightweight chat apps due to its capability to lazy-load your app modules.

• With Angular, it is easy to spot errors in the code and rectify them with ease.

Best Cross-Platform Programming Languages

The chat app you build must be able to operate across different devices, platforms, and operation systems. In order to make it more flexible, your apps should be built with single code that can run on multiple platforms. The solution here is – Cross-platform programming languages.

With no further ado, let us discuss the finest languages for app development.

8. React Native

First on our list is – React Native. As the name indicates, React Native is built with codes that operate with the native UIs easily. Below are the few reasons why React native is a reliable programming language to build cross-platform apps.

• Your code can be reused when written on React Native. This allows you to make only a few changes in pre-written codes and establish new functionalities for the app.

• It follows a modular, component-style architecture making it more organized and easy to use.

• It has native UIs that are flexible enough to be interpreted and presented to the user.

• Uses Javascript to communicate with the native functionalities of the app at runtime.

9. Ionic 

Ionic is a highly versatile framework which runs on top of Apache Cordova. If you’d ask why you must use ionic for your chat apps, here is my list of reasons:

• Ionic helps the development of hybrid mobile apps that can transit user experience from a web app to a native app.

• These frameworks contain a plethora of native compatible tools that’s essential in building apps with dynamic features.

• Since the framework closely relates to the front-end components, they are flexible to add in frameworks from React, React Native, Vue or Angular.

• It takes care of the UI development of your chat app.

10. Capacitor

Similar to Ionic, the capacitor is another framework employed in the development of cross-platform apps. Let’s take a deeper look at its benefits:

• You can easily convert any web app into a native app using the capacitor framework.

• Capacitor is commonly used when apps need access to the native features of a mobile device so that the apps can perform certain functionalities in association with the device features.

• Though created by the same team, Capacitor can function without the need of ionic.

11. Erlang

Erlang is a backend programming language that has lightweight threads used to create a complete process. It’s unique features are as below:

• Erlang is a general-purpose programming language – which means it can be used to create a wide range of app functionalities.

• It is a concurrent programming language. It can handle different processes that run simultaneously within your app.

• Since it has the capability of restarting apps when crashes due bugs or errors, it makes your chat app more reliable and hassle-free.

• The scalability of the language makes it more preferable for building large chat apps.

12. Javascript

Without a doubt, Javascript can run on the backend as well! It can run on the Node environment to support apps at the server side. Here are the reasons why you can consider Javascript for your backend development.

• It consists of a V8 engine that allows your app to process as fast as it can.

• The asynchronous request handling makes processes faster as the client does not have to wait for a response after making a request. Rather, the process will automatically start and keep running.

• Contain a wide range of frameworks, source codes, and plugins.

13. Go

Go or Golang is an open-source, statically typed language that is used to build apps in the backend. If you’d ask why should you use Go as your backend language, here are the list of reasons:

• Supports Automatic Garbage Collection. This supports object memory management by collecting unused objects and destroying them.

• Go is highly concurrent. It can run multiple processes at the same time by using a single function
