Javascript Random Number Generation Method

1. Use the built-in random number generation method:
Math. Random (); // This method generates a floating point number between 0 and 1.
Math. Floor (math. Random () * 10 + 1); // 1-10
Math. Floor (math. Random () * 24); // 0-23

2. Based on Time, random numbers can also be generated:
VaR now = new date ();
VaR number = now. getseconds (); // This generates an integer ranging from 0 to 59 based on the current time.

VaR now = new date ();
VaR number = now. getseconds () % 43; // This generates an integer ranging from 0 to 42 based on the current time.

3.
A fairly good random number generatorProgramAnd can be used in many fields.
