JavaScript: Random number generator

Random.js

Implement a random number generator provided by the Random class. The object interface includes three functions:

• Constructor. Takes a seed, the initial number of the pseudorandom number generator
• getNext() returns a new random number
• reset() resets the generator to the initial value

Export class as default.

Examples

const seq = new Random(100);
const result1 = seq.getNext();
const result2 = seq.getNext();

result1 !== result2; // true

seq.reset();

const result21 = seq.getNext();
const result22 = seq.getNext();

result1 === result21; // true
result2 === result22; // true

Tips

• The easiest way to implement random numbers is a linear congruential generator
