Why You Should Learn Kotlin in 2021

Everybody needs to have their very own app. However seeking to get it off the bottom could be a daunting activity with out figuring out the right way to do it. There are nearly 2.55 million apps on the Google Play retailer and people apps simply hold multiplying. Whether or not you’re beginning out or seeking to broaden your expertise, it’s best to study Kotlin. You may ask, why study Kotlin and never put money into different programming languages? Nicely, let’s break it down.Android app growth isn’t going away anytime quickly. Android OS customers have been steadily rising over the previous decade with decrease entry factors to the ecosystem in comparison with iOS. Android has maintained and improve the bulk market share of smartphone OSs for the previous decade, presently standing at 73%. As for why select to study Kotlin over Java, for instance, the explanations are very clear.


Kotlin for app growth over Java

Straightforward to study

When occupied with beginning to study a brand new language, one of many key components is at all times its problem. For anybody with present developer expertise, understanding and studying Kotlin shall be nearly easy. Kotlin’s syntax and design are easy to understand and but very highly effective to make use of. This can be a key purpose why Kotlin has surpassed Java as being the go-to language for Android app growth.

Interoperable with Java

One of many greatest points with selecting up a brand new language is that if in case you have an present venture or are working as a crew, then there’s a ton of migration to be executed. The fantastic thing about Kotlin is that it’s 100% interoperable with Java. You don’t have to right away cease utilizing Java or swap out all of the code, you should use each. And whereas doing so, including increasingly more Kotlin incrementally so migration is easy.


Extension features provide you with a approach so as to add performance to present lessons (even Java lessons) with out a full rewrite to Kotlin. This implies you may benefit from Kotlin’s highly effective options with out having to desert all the abilities you’ve gained whereas constructing present apps. It permits recovering views from Actions, Fragments, and Views in an amazingly seamless approach. It additionally builds an area view cache. One such extension is ‘Artificial’ Extension.

No extra Null Pointer Exceptions

One of many main points with Java was Null Pointer Exception which results in Android Apps crashing incessantly. Each developer has most likely confronted this drawback. Kotlin, then again, is totally null secure, which prevents this exception from occurring. This benefit alone has prompted many builders to make the change and when you’ve encountered it then you already know.

Dependable and secure

No Null Pointer Exception isn’t the one factor, Kotlin is way extra secure and dependable than Java. The chance of bugs and errors from Kotlin is rather a lot decrease because of preventable points. And errors that do happen are detected throughout compile time itself, which is a good benefit in reliability over Java.

Robust assist

Regardless of it surging in current occasions, Kotlin has been round for a very long time and builders have been making essentially the most out of it. Help has been round and Kotlin is flourishing with the inflow of increasingly more builders, to not point out that it is usually formally supported by Google themselves. Google introduced official assist for Kotlin at Google I/O in Might 2017. And the group is there to assist take advantage of out of it.

There are a lot of sources for constructing your expertise

Apart from the truth that Kotlin is usually tremendous simple to select up and study, there may be an abundance of fine sources to begin your journey. Take a look at our Important Android Sources article that highlights a number of the finest tutorials and bootcamps that may allow you to study Kotlin, in addition to podcasts, communities, and superior tutorials.

Kotlin Multiplatform

JetBrains lately launched Kotlin Multiplatform in 2020, which is a further characteristic of the language that helps it broaden past Android app growth. Kotlin Multiplatform lets builders use a single codebase to develop apps for each iOS and Android. That is the potential game-changer that may actually push Kotlin into being one of many prime languages on the market.

Modular integration: In all probability the largest profit in favor of Kotlin is that it’s an SDK and never a framework. Because of this groups with present apps can merely add a module or migrate a small half to evaluate its viability with out an enormous dedication. This actually helps Kotlin deal with the largest deterrent when shifting to a brand new codebase.

Ease to study: Kotlin as a programming language could be very fashionable already and its syntax is similar to different fashionable languages reminiscent of Swift and Java. This additionally helps scale back the barrier for entry and encourages builders to select up Kotlin instead.

A single codebase for the enterprise logic: Cross-platform growth options by definition allow you to use a single code base for numerous platforms and Kotlin Multiplatform is not any totally different. The benefit of Kotlin is that it helps you to share logic and libraries under the UI layer. This allows builders to straight work together with their native atmosphere (iOS/Android).

Native UI expertise: Kotlin Multiplatform in contrast to different cross-platform choices like Flutter doesn’t demand builders to observe its personal UI. It helps you to make the most of native UI parts to their fullest as in case you are growing natively.

Higher efficiency: This utilization of native elements helps Kotlin developed apps carry out as effectively as they’d as natively developed apps. This can be a a lot sought-after benefit for numerous builders seeking to make one thing past an MVP.

Kotlin Multiplatform cons

Nonetheless in alpha: Kotlin Multiplatform was launched in Kotlin 1.2, however the SDK itself remains to be in alpha. It has stunning adoption in large merchandise(VMware, PlanGrid, CashApp, and Trikot by Mirego), however till a secure launch, corporations shall be hesitant emigrate in the direction of it.

Neighborhood assist and libraries: Being a really new various, libraries and group assist remains to be very restricted and can want catching up. There are just a few fundamental libraries and it’s continually bettering and being labored on.

Not a closed resolution: Kotlin Multiplatform nonetheless wants cell groups to be a minimum of acquainted with the totally different tech stacks. Using a variety of native elements signifies that it gained’t be adequate to be acquainted with solely Kotlin by itself.

The way forward for cell?

We gained’t know for positive if Kotlin is the way forward for cell growth or not. However for now, it’s best to undoubtedly nonetheless decide it up as a language in your toolbox. It’s extraordinarily versatile, highly effective, and straightforward to study! Additionally it is not displaying any indicators of slowing down anytime quickly, so 2021 is the right time to get on the Kotlin prepare.
