import { fn } from "https://deno.land/x/ddc_vim@v4.3.1/deps.ts";
const { srand } = fn;

srand(denops: Denops, expr?: unknown): Promise<unknown[]>

Initialize seed used by rand():

If {expr} is not given, seed values are initialized by reading from /dev/urandom, if possible, or using time(NULL) a.k.a. epoch time otherwise; this only has second accuracy.
If {expr} is given it must be a Number. It is used to initialize the seed values. This is useful for testing or when a predictable sequence is intended.
