Given a String formed only by parenthesis check if they are well balanced (Every parenthesis that opens closes).

parenthesis balanced

var stringGiven    = "(()()(()))",
    auxContainer   = [],
    finalContainer = [];

for(var i=0; i < stringGiven.length; i++){
    if(stringGiven[i] === "("){
        auxContainer.push(stringGiven[i]);
    }
    else{
        if(auxContainer.length){
            finalContainer.push(auxContainer.pop());
            finalContainer.push(stringGiven[i]);
        }
    }
}

console.log(finalContainer.join('').length === stringGiven.length);
