However, while the pseudo-random numbers generated by Math.random() are usually sufficient in most cases, sometimes we need a cryptographically secure source of random number generation. As you may know, it is difficult for computers to generate truly random numbers. This is because it is pseudo-random over time, the numbers will begin to repeat and eventually display a non-random pattern. While there are different ways of using this method to yield random results over certain ranges, Math.random() is not a true random number generator. In mathematical terms, this is represented as 0 <= x < 1. The Math.random() method returns a decimal number or floating-point, pseudo-random number between zero (inclusive) and one (exclusive). The random() method helps us generate random numbers, as the name implies. In JavaScript, we have the native implementation of the random() method in the Math object, a built-in object that has properties or methods for performing mathematical calculations. Typically, we need random numbers for game functions like dice or raffles, private key generation, or other similar programs that require a cryptographically secure source. There are a several use cases in which a program might require a secure source of random number generation. Building a random number generator with JavaScript and Node.js React, Node.js, Python, and other developer tools and libraries. Alexander Nnakwue Follow Software engineer.
