xrand

This is a simple tiny library to generate numbers between two integers (both inclusive) randomly without repetition.

    npm install --save xrand

const Xrand = require("xrand");
 
// supply two numbers to generate unique random numbers
 
const xrand = new Xrand(1, 3);

To generate random number call xrand.generate() method

// to generate a number random number;
 
console.log(xrand.generate());
 
console.log(xrand.generate());
 
console.log(xrand.generate());

after 3 random numbers between 1 to 3 further call to generate returns false

console.log(xrand.generate());

// returns false

const myRand = new Xrand(1, 100);
 
for (let i = 1; i <= 100; i++) {
 
    // this will print 100 numbers between 1 to 100 
    // (both inclusive) randomly without repetition
    
    console.log(myRand.generate());
}
 
// further call to myRand.generate() return false
 
console.log(myRand.generate());

To get all numbers between two integers randomly at once use xrand.generateAll()

 const values = new Xrand(-5, 5).generateAll();
