J.S. HELP: using switch + if statement

Question

var day;
switch (new Date().getDay()){
case 0:
day = "Sunday.";
break;

case 1:
day = "Monday";
break;

case 2:
day = "Tuesday";
break;

case 3:
day = "Wed";
Break;
Document.getEl...("Elem1").innerHTML=day
-- - ------------ -- -- --

Now, I want to add an if statement to say if its case 1, 2, 3, document.getEl..("Elem2).innerHTML = " some text ".

Im trying to group case 1, 2, and 3.
So it's kind of like, when it's the Sunday elem1.innerHTML = " Sunday".
When it's the week, Elem2.innerHTML="text"

Answer 1

On elem 1, it will still display case 0, 1, 2, 3, like normal

elem2 is a different one, it only groups 1,2, and 3. and displays text.
it ignores 0.
