java unable to compare a string with array javascript : I have try different solutions and am unable to figure out why I can't compare a string with array string  is beyond my belief 

here is what I have tried

    function checkWin(){
                let emptyword =["h,","e,","l,","l","o"]
                let computerword= "hello";
                var a = emptyword.join("");
                let b = computerword.toString();
                let c = a.toString();
               
                console.log("computerword :" + b);
                console.log("emptyword is:" + c );
               
                if(b === c)
                 {
                   console.log("someone has won");
        
                 }
                 else if ( b != c)
                    {
                        console.log("b is not same as c");                    
                    }       
        
    }

I am unable to get to "someone has won"  as the condition is never true however when printing the values out in console mode both are the same values ie hello and hello  

any support is most welcome
