Is there a ready-made script for complex reproduction of texts in JS?

Question

JavaScript

Good afternoon, can you recommend a ready-made JS or NPM script for text reproduction with the following parameters:
{text 1|text 2|text 3} - iteration of options
[text 1|text 2|text 3] - permutations
[+separator+text 1| text 2|text 3] - delimited permutations
Command nesting is supported
Thanks in advance.

Answer 1

I'm not sure that I understood you correctly, but for procedural text generation there is tracery (pure random) and Improv (generation based on models or also random).
