Hi, my name is Mario , and I am a professional developer with over 12 years’ experience in the tech/web development industry. During my time doing freelance work, I decided to continue my self-development and assembled a team. I’ve put together a group of highly talented developers which is called the Regulus Team. I wanted to surround myself with intelligent and bright personalities and create a unique brand that offers a better value to clients. Previously, I have held a range of positions ranging from software engineer to CTO. Since then, I have progressed to building and working with large, highly-customized and integrated platforms, becoming an expert in Python, Apache and Nginx configuration, Unix, Typescript, Angular 2+, HTML, coding standards, infrastructure, performance auditing, back-of-house operations, single-page applications, version control, and much more.

What is Kotlin?

With an emphasis on productivity in the tech world, Kotlin has succeeded in taking the programming language expertise to another level.

The developer of software tools at JetBrains is the creator of Kotlin in 2010. Since Java was the mainly used coding language in their products, they set out to develop another computer language basing on their alright tried and tested Java, which would have constructs like higher order functions but be much simpler to program.

Therefore, Kotlin is to be thought of as a measurable, open source android programming language  that can be used for different operating systems such as web, Android, macOS and iOS.

Kotlin vs Java

As we know, Kotlin and Java are interoperable, but they are two different programming languages. So, let’s explore how they differ.

The main difference between Kotlin and Java is the Null Safety, in contrast to Java, Kotlin has built-in null safety. Kotlin also has the advantage of not only making the creation of date classes a lot easier but also extending the functionality of classes compared to Java. 

On the contrary to Java, Katlin has a smart feature that handles the casting checks. Whereas for Java it’s mandatory to specify the type of each variable, in Kotlin it’s quite the opposite.
