Typescript Data Types

Typescript data types

Created By: chatGPT

In TypeScript, data types are essential for defining the structure of your data and ensuring type safety. Here is an overview of the primary data types available in TypeScript:

Boolean: Represents a logical value, either true or false.

let isLoggedIn: boolean = false;

Number: Represents both integer and floating-point numbers.

let age: number = 30;

String: Represents a sequence of characters enclosed in single or double quotes.

let name: string = 'Alice';

Array: Represents a collection of values. You can define an array of a specific type.

let scores: number[] = [85, 90, 78];

Tuple: Represents an array with a fixed number of elements, where each element can have a different type.

let person: [string, number] = ['Bob', 25];

Enum: A special type that allows you to define a set of named constants.

enum Direction { Up, Down, Left, Right }

Any: A flexible type that can hold any value. Use it when you don't know the type ahead of time.

let randomValue: any = 42;

Void: Indicates a function that does not return a value.

function logMessage(message: string): void { console.log(message); }

Null and Undefined: These types represent an empty value or an uninitialized value.

let nullableValue: null = null; let undefinedValue: undefined = undefined;

Understanding these data types is crucial for writing efficient and error-free TypeScript code. By utilizing TypeScript's strong type system, you can catch errors at compile time and provide better documentation for your code.
