A simple Typescript library for generating random numbers and shuffling arrays.

Installation

npm install the-random-ts

Usage

You can use the functions provided by the library in your Typescript project by importing them like this:

import { randomInt, randomArray, shuffleArray } from 'the-random-ts';

Main Functions

randomInt

This function generates a random integer within a specified range. The parameters max and min represent the maximum and minimum values of the range respectively. The function returns a random integer between min and max inclusive. If max is not provided, the function uses the default value of Number.MAX_SAFE_INTEGER and if min is not provided, the function uses the default value of 0.

const randomNumber = randomInt(100, 1); // generates a random number between 1 and 100
const randomNumber = randomInt(100); // generates a random number between 0 and 100
const randomNumber = randomInt(); // generates a random number between 0 and Number.MAX_SAFE_INTEGER

randomArray

This function generates an array of random integers with a specified length, within a specified range. The parameters length, max and min represent the length of the array, the maximum and minimum values of the range respectively. The function returns an array of length random integers between min and max inclusive. If max is not provided, the function uses the default value of Number.MAX_SAFE_INTEGER and if min is not provided, the function uses the default value of 0.

const randomNumbers = randomArray(10, 100, 1); // generates an array of 10 random numbers between 1 and 100
const randomNumbers = randomArray(10, 100); // generates an array of 10 random numbers between 0 and 100
const randomNumbers = randomArray(10); // generates an array of 10 random numbers between 0 and Number.MAX_SAFE_INTEGER

shuffleArray

This function shuffles the elements of an array in place. The function takes an array of generic type T as a parameter and returns the shuffled array.

const originalArray = [1, 2, 3, 4, 5];
const shuffledArray = shuffleArray(originalArray); // shuffles the elements of the array in place
