Converting PHP to Javascript for State Extraction by numeric value Australian State Names

I cant even remember when i originally wrote this php function, but now i need to have it in javascript, should not be much change to it to get it working. 

The original function takes an australian postcode (2000) and returns the state value (NSW, VIC, etc). Not sure if its 100% accurate. 

Australian state and postcode lookup.

Testing

Looks like just one function is missing so far:

What is the javascript for is_numeric? Stack overflow to the rescue here. 

Javascript

function is_numeric(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

Yep just replace that one function, and its working... too easy.

Usage

Just use : console.log(get_state_au("2000"));

or

$state = get_state_au("2000");

passing in your selected postcode. 

Javascript

// i wonder if it will just wor, probably not... lets see. 
	function get_state_au($postcode) {
		$state = false;
		if(!is_numeric($postcode)) { return false; }

		if(($postcode >= 2000 && $postcode <= 2899)) { $state = "NSW"; } // nsw should be checked 1st as act may override it
		if(($postcode >= 2600 && $postcode <= 2618)) { $state = "ACT"; }
		if(($postcode >= 2900 && $postcode <= 2999)) { $state = "ACT"; }
		if(($postcode >= 800 && $postcode <= 900)) { $state = "NT"; }
		if(($postcode >= 4000 && $postcode <= 4999)) { $state = "QLD"; }
		if(($postcode >= 5000 && $postcode <= 5999)) { $state = "SA"; }
		if(($postcode >= 7000 && $postcode <= 7999)) { $state = "TAS"; }
		if(($postcode >= 3000 && $postcode <= 3999)) { $state = "VIC"; }
		if(($postcode >= 6000 && $postcode <= 6999)) { $state = "WA"; }

		return $state;
	}

function is_numeric(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

console.log(get_state_au("2000"));

PHP

// get a state name from an australian postcode
	function get_state_au($postcode) {
		$state = false;
		if(!is_numeric($postcode)) { return false; }

		if(($postcode >= 2000 && $postcode <= 2899)) { $state = "NSW"; } // nsw should be checked 1st as act may override it
		if(($postcode >= 2600 && $postcode <= 2618)) { $state = "ACT"; }
		if(($postcode >= 2900 && $postcode <= 2999)) { $state = "ACT"; }
		if(($postcode >= 800 && $postcode <= 900)) { $state = "NT"; }
		if(($postcode >= 4000 && $postcode <= 4999)) { $state = "QLD"; }
		if(($postcode >= 5000 && $postcode <= 5999)) { $state = "SA"; }
		if(($postcode >= 7000 && $postcode <= 7999)) { $state = "TAS"; }
		if(($postcode >= 3000 && $postcode <= 3999)) { $state = "VIC"; }
		if(($postcode >= 6000 && $postcode <= 6999)) { $state = "WA"; }

		return $state;
	}
                                                   
echo get_state_au("3000");                                                   
echo "<br>";
echo get_state_au("2000");
