Random Number (Float) Generator - Javascript. In this topic, we are going to learn about the Random Number Generator in JavaScript. Almost, every programming language has its built-in function to the same. Different languages do this in different ways, but JavaScript has a function that creates a random floating point value between 0 and 1. By themselves, they can’t do random numbers easier, but as we’ll see, they can still help us. The problem with the Math.random() method that we will be using is that it generates a long, practically useless decimal number such as 0.77180239201218795. Description The nextFloat () method is used to get the next pseudorandom, uniformly distributed float value between 0.0 and 1.0 from this random number generator's sequence. I wanted to animate an element with a random animation-duration. Note that this module uses Math.random() as a base function for a random number generator and therefore it can also be used as a library in your browser..
