Returns true if the prefix array appears at the start of the source array, false otherwise.
The complexity of this function is O(prefix.length).
import { startsWith } from "./mod.ts";
const source = new Uint8Array([0, 1, 2, 1, 2, 1, 2, 3]);
const prefix = new Uint8Array([0, 1, 2]);
console.log(startsWith(source, prefix)); // true
