Different Ways to Achieve Function Composition in Kotlin
<p>Have you ever thought about programming as a bit like playing chess, where every choice you make can lead to either a win or a loss? Well, in the world of coding, function composition is the special technique that lets you blend simple actions together, kind of like how chess pieces come together in a master plan.</p>
<p>Now, picture yourself as a clever chess player in the world of coding with Kotlin. Kotlin offers you a bunch of nifty tools that are a bit like chess tactics — you can mix and match them to create your own coding strategies. In this article, we’re going to explore eight ways to combine functions in Kotlin. It’s a bit like learning different chess strategies, but for coding. These techniques give you various options, depending on how you like to approach your code. So, let’s dive right in and discover how you can juggle functions in Kotlin to make your code even smarter.</p>
<h1>Technique 1: Sequential Composition</h1>
<p><strong>What is it?</strong><br />
This technique calls each function one after the other in a sequence. It’s like following steps in a recipe.</p>
<p><strong>Pros:</strong></p>
<ul>
<li>Simple and easy to understand.</li>
<li>Clear step-by-step execution.</li>
</ul>
<p><strong>Cons:</strong></p>
<ul>
<li>May become verbose with many functions.</li>
<li>Limited flexibility for complex compositions.</li>
</ul>
<p><strong><em>Example:</em></strong></p>
<pre>
fun sayHelloToEveryone() {
hello1()
hello2()
hello3()
hello4()
hello5()
}</pre>
<h1>Technique 2: Nested Function Invocation</h1>
<p><strong>What is it?</strong><br />
Nested function invocation calls one function within another, creating a chain of function calls. It’s like opening a series of nested boxes.</p>
