我的功能无法正常工作（周末）

Question

Can someone help me out with this? It needs to return a yes when filled in Friday, Saturday or Sunday and in all other cases a No. Every time it ends up in "JA"....

code:

    // Nieuwe Array aanmaken dagen
var d = new Date();
var days = ["Zondag","Maandag","Dinsdag","Woensdag","Donderdag","Vrijdag","Zaterdag"];
d.getDay();

// Prompt welke dag
var dag = prompt('Welke dag is het vandaag?');

//functies

function isHetAlWeekend (days, dag)
{
    if ( dag === days[0] || dag === days[5])
    {
        console.log('JA');
    }
    else
    {   
        console.log('NEE');
    }

}

It works fine, test Zondag , Vrijdag or Zaterdag , you will get JA , otherwise NEE

  // Nieuwe Array aanmaken dagen var d = new Date(); var days = ["Zondag","Maandag","Dinsdag","Woensdag","Donderdag","Vrijdag","Zaterdag"]; d.getDay(); // Prompt welke dag var dag = prompt('Welke dag is het vandaag?'); //functies function isHetAlWeekend (days, dag) { if ( dag === days[0] || dag === days[5] || dag === days[6]) { alert('JA'); } else { alert('NEE'); } } isHetAlWeekend(days, dag);
