Test for multiple cases in a switch, like an OR (||)

Question

How would you use a switch case when you need to test for a or b in the same case?

switch (pagei         


        

Answer 1

Forget switch and break, lets play with if. And instead of asserting

if(pageid === "listing-page" || pageid === "home-page")

lets create several arrays with cases and check it with Array.prototype.includes()

var caseA = ["listing-page", "home-page"];
var caseB = ["details-page", "case04", "case05"];

if(caseA.includes(pageid)) {
    alert("hello");
}
else if (caseB.includes(pageid)) {
    alert("goodbye");
}
else {
    alert("there is no else case");
}
