Advanced Functions in Kotlin

This content covers filter, map, let, also, apply, run and with. These functions occupy an important place in the industry and their use is crucial for speed, readability and functionality. These concepts are also known as Collection elements in Kotlin. These are also called scope functions. These functions can be used when dealing with objects and exchanging data via API. They are convenient for use in nullable expressions.


Delegation in Kotlin

Delegation is a way to make composition as powerful for reuse as inheritance. The Delegation pattern has proven to be a good alternative to implementation inheritance, and Kotlin supports it natively requiring zero boilerplate code. Delegation controls the allocation of authority from an instance to another for any object. For classes and functions implementations, delegations can be used on static as well as mutable relations between them. Delegation is used in Kotlin with the help of “by” keyword.


Coroutines

A coroutine is a concurrency design pattern that you can use on Android to simplify code that executes asynchronously. Coroutines were added to Kotlin in version 1.3 and are based on established concepts from other languages. On Android, coroutines help to manage long-running tasks that might otherwise block the main thread and cause your app to become unresponsive. Over 50% of professional developers who use coroutines have reported seeing increased productivity. This topic describes how you can use Kotlin coroutines to address these problems, enabling you to write cleaner and more concise app code.


Flow Operators

Blandit adipiscing eu felis iaculis volutpat ac adipiscing accumsan eu faucibus. Integer ac pellentesque praesent tincidunt felis sagittis eget. tempus euismod. Vestibulum ante ipsum primis sagittis eget. tempus euismod. Vestibulum ante ipsum primis in faucibus vestibulum. Blandit adipiscing eu felis iaculis volutpat ac adipiscing accumsan eu faucibus. Integer ac pellentesque praesent tincidunt felis sagittis eget. tempus euismod. Vestibulum ante ipsum primis in faucibus vestibulum. Blandit adipiscing eu felis iaculis volutpat ac adipiscing accumsan eu faucibus. Integer ac pellentesque praesent. Vestibulum ante ipsum primis in faucibus magna blandit adipiscing eu felis iaculis.


Collections in Kotlin

Lorem ipsum dolor sit accumsan interdum nisi, quis tincidunt felis sagittis eget. tempus euismod. Vestibulum ante ipsum primis in faucibus vestibulum. Blandit adipiscing eu felis iaculis volutpat ac adipiscing accumsan eu faucibus. Integer ac pellentesque praesent tincidunt felis sagittis eget. tempus euismod. Vestibulum ante ipsum primis sagittis eget. tempus euismod. Vestibulum ante ipsum primis in faucibus vestibulum. Blandit adipiscing eu felis iaculis volutpat ac adipiscing accumsan eu faucibus. Integer ac pellentesque praesent tincidunt felis sagittis eget. tempus euismod. Vestibulum ante ipsum primis in faucibus vestibulum. Blandit adipiscing eu felis iaculis volutpat ac adipiscing accumsan eu faucibus. Integer ac pellentesque praesent. Vestibulum ante ipsum primis in faucibus magna blandit adipiscing eu felis iaculis.


Clean Code and Solid Principle
