Ruby on Rails

Do you see any error on the browser's console? first thing I notice just simple looking at it is it's missing all the ; at the end of the lines, maybe you have a syntax error on the browser's dev tools

$(document).on('turbolinks:load', function () {

})

submit_messages = function () {
    $('#message_content').on('keyDown', function (event) {
        if (event.keyCode === 13) {
            $('input').click()
            event.target.value = ''
            event.preventDefault()
            console.log('yes we hit enter!')
        }
        
    })
    
}

I got this from a youtube video titled Rails 6 - Real Time Chat App What doesn't make sense to me is why do we only clear the field if the enter key is pressed, why doesn't that work anyway (it doesn't clear the field) and why doesn't it log to console 'yes we hit enter!'
