You have Arizona and Kentucky listed twice.

👍 Thanks for this. Saved lots of typing.

Thankfully, Canada and the US have distinct abbreviations, so this can easily be extended for US+Canada support. Additionally, duplicates (Arizona and Kentucky) have been removed and recognized US regions that are not states have been added (e.g. Armed Forces ___).

function abbrRegion(input, to) {
    var states = [
        ['Alabama', 'AL'],
        ['Alaska', 'AK'],
        ['American Samoa', 'AS'],

I made some updates to mdmower's code above. I am using constants to make the code easier to read, and also changed the function name.
It would be called like this:

var stateName = convertRegion("TX", TO_NAME);
var stateAbbr = convertRegion("Texas", TO_ABBREVIATED);

It's cleaner and easier to read, in my opinion.
Here is my version of the code:

const TO_NAME = 1;
const TO_ABBREVIATED = 2;

function convertRegion(input, to) {
    var states = [
        ['Alabama', 'AL'],
        ['Alaska', 'AK'],
        ['American Samoa', 'AS'],
        ['Arizona', 'AZ'],
        ['Arkansas', 'AR'],
        ['Armed Forces Americas', 'AA'],
        ['Armed Forces Europe', 'AE'],
        ['Armed Forces Pacific', 'AP'],
        ['California', 'CA'],
        ['Colorado', 'CO'],
        ['Connecticut', 'CT'],
        ['Delaware', 'DE'],

Very good time saving function. Thanks for sharing.

ksullivan91 · 2018-01-18T20:26:44Z

Thank you, sir.

LawJolla · 2018-08-27T22:50:14Z

Really helpful, thank you!

Here's my code for the function -- it removes the need for to parameter -- if it helps anyone.

function abbrState(state) {
  ...
  const selectedState = states.find(s =>
    s.find(x => x.toLowerCase() === state.toLowerCase())
  )
  if (!selectedState) return null
  return selectedState
    .filter(s => s.toLowerCase() !== state.toLowerCase())
    .join("")
}

Most of these solutions add unnecessary complexity without significant improvement in speed, readability, reliability, or usefulness. @davidteather is on the right track. Here's the "inverse" of his solution, for converting from a state name into an abbreviation. It's simple, fast, and readable.

function stateNameToAbbreviation(name) {
	let states = {

		"guam": "GU",
		"northern mariana islands": "MP",
		"puerto rico": "PR",
		"us virgin islands": "VI",

	}

	let a = name.trim().replace(/[^\w ]/g, "").toLowerCase(); //Trim, remove all non-word characters with the exception of spaces, and convert to lowercase
	if(states[a] !== null) {
		return states[a];
	}

	return null;
