what to use instead of document.write in javascript for a function

Question

function begroeten(){
let vandaag = new Date();
let uur = vandaag.getHours();
if (uur >= 0 && uur <= 15){
    document.write('Goedemorgen!');
   
}
else if  (uur >= 12 && uur <= 23){
   document.write('Goedemiddag!');
    
} }

I want to get the result from the function on javascript in my website without using document.write.
