Scala vs Kotlin is a well-known programming language. As we know the big famous companies Google, Amazon, Netflix, Pinterest, Uber, and others use the Kotlin programming language for their android applications than scala. Is there a secret behind all this? Let’s find out why in this article.

Kotlin vs Scala: Most Popular Technologies

Kotlin Vs Scala

Data from a stack overflow survey showed that the programming language Kotlin is superior to Scala. It becomes a big question why the Kotlin language is so popular among android developers. Why is the programming language Kotlin more widely used than Scala? We have investigated several articles that discussed the same thing regarding Kotlin and Scala.

Benedikt Jerat, a scala developer, said that “Scala programming language code is very incomprehensible, complicated, and difficult to read.” This is also strong evidence of why this programming language is not competing with Kotlin.

Continuing his discussion, he said that Scala and Kotlin have different levels of programming. The factor that sets the levels apart is that Kotlin has guidelines that closely follow the typical times and patterns among developers. Kotlin is still object-oriented and functional enriched with many concepts that Java developers have been waiting for.

In contrast to Scala, it has a different mindset from java. Kotlin has succeeded in making java developers comfortable with code. Able to work effectively and quickly. The combination of java and Kotlin is something to look forward to in a large project because it has broad compatibility. In addition, developers can type safely without having to worry about errors.

Quoting from Benedict’s snares:

“Scala was not designed with Java interoperability as a primary goal: simply a byproduct of running on the JVM.”

Kotlin vs Scala: Most Used in Android apps

Based on data on stack share regarding companies that use Kotlin or Scala, it is found that the majority use the Kotlin programming language rather than Scala. The number of companies using Kotlin is 1250, while scala is only 937. This seems to be a common reason why Kotlin is so widely used over Scala.

Weaknesses in Scala are challenging to understand and difficult to read into a negative review that influences other companies to use the programming language.

But What are Kotlin and Scala Actually Meant For?

Taken from a review of a major company that uses the Kotlin programming language:

“I focus mainly on mobile apps, so it’s clear there that it will be a native app written in Kotlin.” – Karin Polačíková (Mobile Developer)

“We initially wrote a lot of networking code in Kotlin, but the complexities involved prompted us to try and compile NodeJS for Android. This turned out to be a great decision considering our battery usage fell by 40% and rate of development increased”. – Omran Jamal (CTO & Co-founder at Bonton Connect)

“If software performance is your top priority, then Scala/Play is probably best.” – Meam Software Engineering Group.

“You can use Scala for small services and Data Engineering stuff and benefit optimizations and threading of JVM.” –Senior Software Engineer.

The conclusion obtained in the review from 2 points of view between businesses that have used it and senior developers is that there is a difference between Kotlin and Scala. Kotlin is used for the development of mobile apps. When combined, using Node Js for android can reduce battery reduction by 40%. Battery usage is often the most significant factor in choosing apps and user issues. In contrast to Scala, Scala prioritizes software performance.

Kotlin Will Follow Typescript Popularity

According to the JetBrains report, half of all developers polled intend to adopt a new programming language, with Go and Rust being the most popular, followed by Kotlin, TypeScript, and Python.

As a result, Kotlin is popular, gaining ground on other languages, loved by more developers and feared by fewer. Other key findings presented by JetBrains in the new report include:

  • Among the promising technologies for developers are AI/ML, Rust, JavaScript, Go, Kotlin, and Blockchain.
  • PHP, Ruby, Objective-C, and Scala are among the programming languages that are losing popularity.
  • Working from home is still an option for most developers, with 76 percent preferring to work primarily from home.
  • Remote collaborative programming is used by 50% of developers.
  • Only 57 percent of employed survey respondents are satisfied with their salaries, although 69 percent are satisfied with their jobs.
  • Burnout has affected 73% of developers at some point in their careers.
  • A referral from a friend is the most common method of obtaining a job. This is how 30% of survey respondents found work.

According to the methodology, the report’s method is based on the contributions of 29,269 developers from 187 nations and regions, including two responses from Antarctica. The data were weighted depending on the report’s specified criteria.


Kotlin vs. Scala comparison can be your reference in choosing the correct programming language for your application development. All depend on the output generated from the programming language. It can be in the form of speed, benefits that are felt directly by application users, and the ease of your developers in implementing programming languages.
