- What is the largest number I can generate?
- You can use values up to JavaScript's safe integer limit, which is 9,007,199,254,740,991 — far more than most people need.
- Is the result truly random?
- It uses pseudo-random number generation via Math.random(), which is sufficient for games, sampling, and everyday use. It is not suitable for cryptographic purposes.
