MTwist

• A concise Mersenne Twister implementation in CoffeeScript/JavaScript
• Includes the 2002 initialization improvements
• Tested against the original C implementation

Why would I use this?

• You want to be able to seed your random number generator to create reproducible sequences
• You want to know exactly how your random numbers are generated across all JS engines

How do I use this?

x = Math.random();

becomes

seed = 1234567890;  // an integer between 0 and 4294967295
m = new MTwist(seed);
x = m.random();

Methods to produce evenly distributed integers in the ranges [0,n) and [m,n] are also provided.
