* Make an assertion that `actual` and `expected` are equal, deeply. If not

* Type parameter can be specified to ensure values under comparison have the

* same type.

* @example
|
|
* ```ts ignore
|
|
* import { assertEquals } from "@std/assert";
|
|
*
|
|
* assertEquals("world", "world"); // Doesn't throw
|
|
* assertEquals("hello", "world"); // Throws
