CODE EXAMPLE FOR JAVASCRIPT

jquery on method

 //more flexible way of adding an event listener;
 //using the .on method
$('h1').on('mouseover', function(){
    $('h1').css('color', '#'+Math.floor(Math.random()*16777215).toString(16));
})//the above changes your h1 elements color property to a random color
//but other events can be used as well. see source and below
//Guess what this does
$(document).on('keypress', function(event){
    if (event.key === 'a') {
        console.log('move left function...');
        $('h1').css('color', '#'+Math.floor(Math.random()*16777215).toString(16));
      }     
})

//Answer Below





//everytime you press 'a' the text in your h1 becomes a different color
