.

 Introduction

The app development business is growing fast with an increasing number of smartphones. According to recent studies, the mobile app business is predicting a boom of over 900 billion in 2023. Studies like this demonstrate how creating an app is vital for your business to remain afloat. But making an app is also a tricky task. Selecting a suitable coding language and a development firm that fits your business and budget is crucial.

In this blog, you will get brief details about Kotlin and a comparison with other coding languages to clear any further confusion. By the end of this blog you will get a perfect idea of why to use Kotlin in 2023 for app development.

 What is Kotlin?

Kotlin is an open-source, statically typed modern programming language. A general-purpose language that is used for making multi platform app development, website development, and back-end development. It’s easy to say that Kotlin is an improved version of Java that fully interoperates with Java. Kotlin is versatile, easy to code, and safer.

Kotlin is versatile and secure, making it a first choice for developing apps for several brands. Here is a list of the big brands that used Kotlin for app development.

History of Kotlin

What makes it interesting is the comeback of Kotlin after hiding under the shadows for years. It rose to popularity just about the time when Google officially announced that Kotlin was their preferred language for Android app development in 2019.  

Kotlin was initially introduced by JetBrains in 2011. JetBrains is a software development company based in the Czech Republic, Russia. They have been working with Java for years and wanted something different. An advanced language that can overcome the limitations of Java without hindering performance and security. To make a better Java Project, Kotlin started in 2010 as an open-source language. Later in July 2011, JetBrains unveiled Project Kotlin to the world.

The first official Kotlin 1.0 was released on February 15, 2016. The current version of present Kotlin is 1.8.20, published on April 3, 2023

Kotlin Features

.

After a quick history recap, let’s understand what types of features Kotlin packs that makes it a preferable choice compared to any other language. 

Kotlin is Safe and secure

The demanding part for any developer is to go through the testing phase and make any code secure. With the help of using programming languages like Kotlin, there is lower risk because of the null safety feature offered.

While making an app, Developers use "variables" to store information. Sometimes, these variables don't have any information, making them null.

Kotlin helps you prevent mistakes when dealing with these empty variables so you do not accidentally use them when you're not supposed to. Making the app less likely to crash or have errors. Features like this make Kotlin safe and secure and help to develop a robust error-free app that leads to better-built development.

interoperability with Java

As we discussed earlier, the creators made Kotlin to overcome the limitations of Java. Not only does Kotlin constrain the boundaries of Java, but it also works with Java codes. This means you can use it with all the Java code already out there, making it interoperable with Java.

Kotlin helps make your code future-proof, which is essential for business owners. For instance, if you made an app using Java in the past, but now you want to make changes to follow the latest trends, you can use Kotlin. Kotlin is interoperable with Java, which means that developers can modify the code for you, making it safer without affecting the quality. This way, you can ensure that your app stays up-to-date without worrying about the underlying code.

Do you know: "Leading brands like Pinterest, Uber, Kickstarter, Evernote, and many more migrated from Java to Kotlin because of the benefits Kotlin provides."

Lower cost of making

Using Kotlin to develop an app can be a cost-effective solution for businesses. Kotlin's syntax is more concise than Java, which translates to writing the same amount of code in fewer lines. 

Features like null safety and extension functions make code more reliable and efficient, reducing errors and the need for costly debugging and maintenance.

Having to write less code and being less prone to errors means it reduces the time and effort required to develop an app, resulting in lower development costs.

Compact and cleaner syntax

Kotlin's code is easy to read and write, making the syntax more compact and cleaner. That means that hiring remote developers can work faster with fewer mistakes. By reducing errors and bugs, you can save money, as we talked about earlier in the last point. 

Another thing to consider is the syntax of Kotlin is like modern programming languages, making it easier for businesses to find skilled remote developers. And the features offered make it easier to maintain and scale.

Quick facts: "Kotlin uses less code than Java. For a rough estimate it uses 40% less code than Java translates to faster development."

Open-Source nature of Kotlin

Kotlin's open-source nature is a great asset for businesses looking to build an app. Firstly, it's free to use, which means companies can build high-quality apps without worrying about licensing fees. Secondly, the language is being updated and improved by a large community of developers, which makes it more stable and secure.

Being open source also means that it will get frequent updates, translating to low maintenance and more stability for an extended period.

Finally, the open-source nature of Kotlin helps developers to work together. For example, your company is working on developing an app, but you want more workforce to complete the task. You can hire a remote developer who can collaborate with your team without coding barriers.

Kotlin vs Java
