How to use
Shuffle uses browser cryptographic randomness by default. Enter an optional seed when you need the same input and seed to produce the same order again.
Example
Input
north
east
south
west
Output
north
east
west
south
Limitations
Random order is not a fairness guarantee. A seeded shuffle is deterministic and is not cryptographically random.
Frequently Asked Questions
Will repeated entries be deduplicated?
No. Each source line occupies one position in the shuffled result.
Why use a seed?
A seed makes a shuffle reproducible for lesson plans, test fixtures, or shared lists.
