Can I use (Switch/Case) statement for an array? (JavaScript)

Question

I want to use Switch/Case statement for an array. For example :
var arr = ["Item1","Item2", "Item3",......];
switch (arr)
{
case arr[0]:
//print something
break;
case arr[1]:
//print something
break;
case arr[2]:
//print something
break;
}
Is it possible? If possible, then what is the right way?

Answer 1

var arr = new Array("a", "b", "c");

var key = "b";

switch(key){
case arr[0]:
console.log("a");
break;
case arr[1]:
console.log("b");
break;
case arr[2]:
console.log("c");
break;
}

Code playground is self explanatory.
Do a code. And check if it works or not.

Maybe your code will give an error because you used same arr in switch and case both.
My code will work for you as example.

Raj Chhatrala I had tested the code. But it gave me an error. Btw thanks for your answer!

Answer 4

An array may consist of multiple values and switch is able to perform equality checking at one value at a time.

Otherwise, a loop might be required.

Meanwhile, can you further elaborate on what are you trying to achieve with switch?

Because you've referred the array twice using switch in 2 different way and the switch statement can only evaluate a value inatead of an entire array.

Answer 5

I think its possible

Answer 6

Notece:
!!(arr == arr[0]); // false
!!(arr == arr[1]); // false
!!(arr == arr[2]); // false
None case never will to be able to run.
