Math.random() is a PRNG, not a CSPRNG. An attacker who observes a few outputs can predict every future call. I found this exact pattern generating API keys in a 44K-star open-source codebase. Here is why it matters and the ESLint rule that catches it.

The Abstract: Large language models (LLMs) increasingly excel at mathematical reasoning, but their unreliability limits their utility in mathematics research. A mitigation is using LLMs to generate formal proofs in languages like Lean.…

The Markov property for a stochastic process X(t) essentially tells you that knowing the value of the process at a time s ≤ t is just as good as knowing the entire history of the process up to time s for making predictions about X(t).…
