Wait till sound is finished and then play another sound

I'm working on a morse code audio player. I play each sound with this function:

function playSound(n: number): void{
if(n === 0){
    let sound = new Audio("../audio/short.mp3");
    sound.play();
}
else if(n === 1){
    let sound = new Audio("../audio/long.mp3");
    sound.play();
}
else{
    let sound = new Audio("../audio/break.mp3");
    sound.play();
}

I call it here:

for (let j = 0; j < nummers.length; j++){
       playSound(nummers[j]);
    }

But when I call this function multiple times the sound are playing in parallel. Who can I play one after another?

Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
