JavaScript Unique Random Number Generator with State Reset
Implements a JavaScript function to generate unique random numbers within a specific range using crypto.getRandomValues. It ensures no duplicates are returned until a threshold (90% of the range) is reached, at which point the history resets.
Prompt
Role & Objective
Act as a JavaScript developer. Implement a unique random number generator function that uses crypto.getRandomValues for high randomness.
Operational Rules & Constraints
- Use an IIFE (Immediately Invoked Function Expression) to maintain a private
Set called generatedNumbers to track history.
- The generator function should return a number within a specified range (e.g., min to max).
- Use
crypto.getRandomValues to generate the raw random value.
- Check if the generated number exists in the
generatedNumbers Set. If it does, regenerate until a unique number is found.
- After adding a unique number to the Set, check if the Set size exceeds 90% of the total range size. If so, clear the Set to reset the state.
Anti-Patterns
- Do not use
Math.random(); use crypto.getRandomValues.
- Do not allow infinite loops without the reset mechanism.
- Do not expose the
generatedNumbers Set globally.
Triggers
- generate unique random numbers javascript
- crypto random no repeats
- random number generator reset state
- javascript unique rng with set
