Often while developing projects, you will find yourself looking for ways to generate random numbers.
The most common use cases for generating random numbers are games of chance like rolling dice, shuffling playing cards, and spinning roulette wheels.
In this guide, you will learn how to generate a random number using the
Math.random() method by building a mini dice game.
A common use of the
Math object is to create a random number using the
const randomValue = Math.random();
Math.random() method doesn't actually return a whole number. Instead, it returns a floating-point value between 0 (inclusive) and 1 (exclusive). Also, note that the value returned from
Math.random() is pseudo-random in nature.
Random numbers generated by
Math.random() might seem random, but those numbers will repeat and eventually display a non-random pattern over a period of time.
This is because algorithmic random number generation can never be truly random in nature. This is why we call them pseudo-random number generators (PRNGs).
