How to nest OR statements in JavaScript?

Is there a way to do this:

 if( variable1 == (variable2 || variable3 || ...) )

I need to check if variable1 is equal to either variable2 variable3 4 5…

I can’t directly do this:

 if( (variable1 == variable2) || (variable1 == variable3) || ...) )

because I don’t know exactly how many variable2 3 4 5… I have

btw variable2 3 4 5… are the elements of my array. I tried this but nothings happen.

if( variable1 == (variable2 || variable3 || ...) )

update:
here’s the snippet

let say strskill equal to:

abc|def|ghi|jkl|

.

 var myskl = document.getElementById('strskill').value.split("|");


 for(var q=0; q<(myskl.length); q++)
        {
            var r = r + "myskl[q], ";
            var s = r + "myskl[q]";             
        }

        if(s.indexOf(myArray[i]) > -1)
        {   
            continue;
        }   

I tried your suggestion, but still not working!

You could also do it this way

a = 1;
b = [1,2,3,4];


function check(a,b){
    i = 0;        
     for (i=0;i<b.length;i++) {
        if (a === b[i]) {
             return true;
        }
    }
    return false;
 }

alert(check (a,b))
