/**
* Join all given a sequence of `paths`,then normalizes the resulting path.
*
* @example Usage
* ```ts
* import { join } from "@std/path/posix/join";
* import { assertEquals } from "@std/assert";
*
* const path = join("/foo", "bar", "baz/asdf", "quux", "..");
* assertEquals(path, "/foo/bar/baz/asdf");
* ```
*
* @example Working with URLs
* ```ts
* import { join } from "@std/path/posix/join";
* import { assertEquals } from "@std/assert";
*
* const url = new URL("https://deno.land");
* url.pathname = join("std", "path", "mod.ts");
* assertEquals(url.href, "https://deno.land/std/path/mod.ts");
*
* url.pathname = join("//std", "path/", "/mod.ts");
* assertEquals(url.href, "https://deno.land/std/path/mod.ts");
* ```
*
* Note: If you are working with file URLs,
* use the new version of `join` from `@std/path/posix/unstable-join`.
*
* @param paths The paths to join.
* @returns The joined path.
