Generate Number With Random In JS

// (0, 1)
Math.random();

// (0, max)
Math.random() * max

// (min, max)
Math.random() * (max - min) + min

// (0, 1) no integer between 0 and 1

// (0, max)
parseInt(Math.random() * max); // include 0, but not include max
parseInt(Math.random() * (max + 1)); // include 0 and max

// (min, max)
parseInt(Math.random() * (max - min) + min); // include min, but not include max
parseInt(Math.random() * (max - min + 1) + min); // include min and max
