Hello there! Today is a milestone as we step into Kotlin, a user-friendly, yet powerful language, popular in mobile and web programming spheres. This lesson will acquaint you with the basics of Kotlin, including syntax, comments, and writing your first print
statement — fundamental concepts for entering the Kotlin world.
Understanding a language starts with its syntax — the structure and rules that govern how the code is written — which serves as the backbone of any programming language. For instance, let's consider this straightforward Kotlin statement:
println
is a built-in Kotlin function that prints the argument provided to it. In our case, the argument is the string "Hello, World!".
Comments are crucial in coding as they improve the readability of your code, making it easy to understand not only for others but for you as well in the future. Comments are added with the purpose of making the code easier for humans to understand, and they do not affect the code execution in any way. Kotlin offers both single-line and multi-line comments.
Here is a single-line comment:
Multi-line comments spread across multiple lines and are enclosed within /* */
:
Think of comments as notes in your coding diary — they explain your code and enhance its comprehensibility.
