Kotlin Collections vs Sequences in Just 5 Minutes

Let’s understand the difference between Collections and Sequences with a simple example:

val operations = (1..10)
    .filter{it % 2 == 1}
    .map { it * 2 }
    .take(2)

Collections

In the above collection operations, we first loop through numbers from 1 to 10, then create a collection of numbers who are odd, then create another collection by multiplying the elements of previous collection by 2 and then create a collection by taking first 2 elements of previous collection.

For the above example with collections, the results at each step would be as follows:

val operations = (1..10) 
    .filter { it % 2 == 1 } // 1, 3, 5, 7, 9
    .map { it * 2 }        // 2, 6, 10, 14, 18
    .take(2)               // 2, 6

Now, let’s take a look at the map function for Collections.

Kotlin or React Native | React Native vs Kotlin Performance Comparison

Mobile app development has now become a cornerstone of successful market differentiation, growth, innovation, profitability, and collaboration. Several enterprises are now aggressively adopting mobile technologies to achieve business objectives. In order to meet the rapidly fluctuating business requirements and business needs, there are several different platforms and technologies.

It has become a point of debate to choose the right technology to accomplish objectives. More and more organizations are adopting cross-platform mobile app development services to build mission-critical mobile apps to expand the business.

If you are planning to launch a new mobile application, it is about time to compare the two most favorable frameworks-React Native vs Kotlin to help you understand the advantages and drawbacks. This quick analysis will help to decide whether to opt for cutting-edge Kotlin Application development services or React Native development services.

Kotlin

Designed by JetBrains

Launch 22 July 2011; 9 years ago

Sponsored and developed by JetBrains, Kotlin is a programming language that runs on the Java virtual machine and can be compiled to JavaScript source code or use the LLVM compiler infrastructure. After being endorsed by Google as the official language for Android Studio, Kotlin has consistently gained popularity.

Backed by JetBrain, Kotlin is responsible for creating the best IDE tools. Kotlin provides phenomenal support in a different development environment such as Android Studio. Selecting Kotlin app development for your Android project provides support across multiple tools and IDEs.

Kotlin code is not only precise and concise but also has an extremely clear codebase. That leaves fewer chances for errors and allows stable code in production. You have to write fewer lines of code to achieve the same functionality.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
