Zip code validation

These are a few examples of how to validate various zip code formats.

In the following examples, A represents any letter and 9 means any number.

	// ============
	// Helper: log.
	// ============

	const log = (error) => {
	console.log(error?.message \|\| error);
	}

	// ===============
	// Promise reject.

	require('@testing-library/jest-dom');

	// Override.
	Object.defineProperty(window, 'requestAnimationFrame', {
	writable: true,
	value: (f) => {
	if (typeof f === 'function') {
	f();
	}
	},

	<script lang="ts">
	// ======
	// Props.
	// ======

	const { Component, slot, ...otherProps } = $$props;
	</script>
