Focus on input to display a console log message from if/if else conditional?

I'm stuck as to why when I "focus" on the input, it doesn't display my console log message unlike if it's empty or not empty, it'll display the message. Am I using the event wrong?

(Only a portion of my code, if needed more details, please let me know)

The HTML

<input id='input' placeholder="President Name" type="text"> 

The JS

function message() {
   var presidentInput = document.getElementById('input').value;
            if (presidentInput === "") {
                console.log('Please enter something in the input');
            } else if (presidentInput !== "" || document.getElementById('input').onfocus){
                console.log('Great job');   
            }
        }
message();
