The Math object, a built-in object with attributes or methods for carrying out mathematical operations, has the native implementation of the random() method in JavaScript. As its name suggests, the random() method aids in the generation of random numbers. The return value of the Math.random() method is a floating-point, sort of semi number between 0 (inclusive) and 1. (exclusive). This is defined mathematically by the equation 0 = x 1. The Math.random() function will return a floating-point, pseudo-random number in the range 0 to less than 1 (inclusive of 0 but not 1) with an essentially uniform distribution throughout that ...
