The comma and the "less than" symbol are both on the same key. I'd like to have a JS function run when a comma is typed, but not a less than symbol. Is there a different/better approach than:

if (e.keyCode == 188) {
  // Run some code

Here's a simple solution that will catch all characters, backspace, and delete. 

$("input").keydown(function(event) {
    var isWordCharacter = event.key.length === 1;
    var isBackspaceOrDelete = event.keyCode === 8 || event.keyCode === 46;
    if (isWordCharacter || isBackspaceOrDelete) {
        // do something
