SKT: Types, Numbers, Booleans, and Strings

In the modern world of app and web development, three languages are making waves: Swift, Kotlin, and TypeScript (SKT). While each has its own domain (iOS, Android, and Web, respectively), they share fundamental concepts, especially when it comes to basic data types. Let's take a quick tour through numbers, booleans, and strings in these powerful languages.

Types: The Foundation

All three languages are statically typed, meaning you explicitly (or implicitly) define the type of a variable. This helps catch errors early and improves code readability.

Swift: Known for its type safety, Swift strongly encourages explicit type declarations.

Kotlin: Like Swift, Kotlin is statically typed and offers type inference, reducing boilerplate.

TypeScript: Built on JavaScript, TypeScript adds static typing, making large JavaScript projects more manageable.

Numbers: Handling Numerical Data

Numbers are essential for calculations and data manipulation.

Swift:

Swift provides various numeric types: Int (integers), Double (floating-point numbers), and Float.

let integerValue: Int = 10
let doubleValue: Double = 3.14

Kotlin:

Kotlin's numeric types are similar to Java's: Int, Double, Float, Long, Short, and Byte.

val integerValue: Int = 10
val doubleValue: Double = 3.14

TypeScript:

TypeScript has a single numeric type: number, which can represent both integers and floating-point values.

let numericValue: number = 10;
let floatValue: number = 3.14;

Booleans: Representing Truth

Booleans represent true or false values, crucial for conditional logic.

Swift:

Swift uses Bool for boolean values.

let isTrue: Bool = true
let isFalse: Bool = false

Kotlin:

Kotlin uses Boolean.

val isTrue: Boolean = true
val isFalse: Boolean = false

TypeScript:

TypeScript uses boolean.

let isTrue: boolean = true;
let isFalse: boolean = false;

Strings: Working with Text

Strings represent sequences of characters.

Swift:

Swift uses String for text.

let message: String = "Hello, Swift!"

Kotlin:

Kotlin uses String.

val message: String = "Hello, Kotlin!"

TypeScript:

TypeScript uses string.

let message: string = "Hello, TypeScript!";

Common Ground, Different Paths

While Swift, Kotlin, and TypeScript cater to different platforms, their handling of basic data types reflects a shared understanding of fundamental programming concepts. Understanding these similarities makes it easier to transition between these powerful languages.
