Dart Overview
What is Dart?
Dart is a widely used, modern Object-oriented programming language with powerful features and tools. Dart was developed by Google in the year 2011 to simplify complex web applications. Soon after it was used widely for multi-purpose languages including mobile applications, desktop applications, server-side programming, and more. Dart is backed by Google which makes it more trustworthy among the developers with its rich ecosystem and large community. Its type-safety and null safety features make it more powerful and efficient for application development.
Key Features
- Static typing and Optional typing Support: Dart supports Static and Dynamic typing, with Static typing data type of variables is known at compile time which eliminates runtime typing issues, While dynamic typing gives flexibility to check variable type at run time.
- Powerful Asynchronous mechanism: Dart has built-in support of Asynchronous operations through its await/async keyword. This feature enables the development of responsive and scalable applications by managing asynchronous operations easily and efficiently.
- Object-Oriented Programming principles support: Dart is an Object-Oriented Programming language, which means it sports core Object-Oriented pillars – Inheritance, Abstraction, Polymorphism, and Encapsulation. This helps in writing code in such a manner that it helps developers reuse and manage code more easily.
- Support of Flutter Framework: Flutter is a very popular open-source cross-platform that allows developers to build natively compiled applications for mobile, web, and even desktop from a single codebase. Flutter’s hot reload feature and its expressive syntax feature accelerate cross-platform application development with a single code base.
- Interoperability with JavaScript: Dart supports seamless interoperability with JavaScript which means it allows developers to use existing JavaScript libraries and Framworks. This interoperability enables the integration of Dart code with web apps and other JavaScript-based platforms.
Advantages of Dart Language
- Dart is backed by Googe, which benefits from a growing community and rich ecosystem that offers detailed tutorials and documents.
- It supports automatic memory management using a garbage collector that eliminates the need for developers to handle memory manually.
- Dart supports natively compiled applications with the use of Ahed-Of-time(AOT) compilation which enables high-performance mobile application development.
Kotlin Overview
What is Kotlin?
Kotlin is a modern programming language developed by JetBrains, It was first introduced in 2011 as an alternative to Java, targeting the Java Virtual Machine (JVM). Initially, Android was launched to be used as a plugin in Android Studio, but later in May 2017, Kotlin was declared as the official Android Development language. The goal behind introducing Kotlin was to address various lacking features in existing programming languages, particularly Java while maintaining seamless interoperability with Java. Kotlin is not limited to Android development but is also used in other software development domains, such as backend development, desktop application development, and data science and analytics.
Key Features
- Concise code and readability: Kotlin is well known for its concise syntax that helps developers reduce boilerplate code, which makes code very easy to understand and more readable.
- Null Safety Support: One of the powerful features of Kotlin which is widely used is its Null Safety feature, which distinguishes Nullable and non-Nullable types. This feature enables developers to prevent null pointer exceptions which is a very common issue in programming languages.
- Interoperable with Java language: Kotlin is fully interoperable with Java language, which allows developers to use existing Java libraries and frameworks seamlessly. This interoperability makes it easy to adopt Kotlin in projects with an existing Java code base.
- Large-scale audience adoption: Continue contributions of developers to its plugin and library making its community large and strong. Kotlin’s ecosystem has grown significantly in recent years.
- Coroutines support: Manage asynchronous tasks with Kotlin in a very easy and effective manner Kotlin comes up with the most powerful feature – Coroutines. Coroutine comes up with suspend functions that allow developers to pause and resume background processes.
Advantages of Kotlin Language
- With the use of extension functions, Kotlin allows developers to add new methods to existing classes without modifications in those classes.
- Apart from Android developers, back-end developers are also moving towards Kotlin due to its features like null safety and conciseness.
- Kotlin came up with Coroutines, which has made asynchronous programming more easy and readable compared to the traditional callback-based approach.
