TODO By for JavaScript

todo-by.js

// Inspired by https://github.com/andyw8/do_by
// Usage:
//    TODO( 'Finish this feature', 'Decemeber 25, 2015' );
//    TODO( 'Finish this feature', '12/15/2015' );

this.TODO = function () {
  var message = arguments[0];
  var date = arguments[1] || false;

  // TODO only set the hours to zero if no time is provided in the TODO
  if ( new Date( Date.parse( date ) ) < ( new Date() ).setHours( 0, 0, 0, 0 ) ) {
    throw new Error( message + ' is past due! Should have been completed by ' + date );
  }
}

Should be able to easily make this an NPM and Meteor package.
