Find the opening and closing element?

• 0
  I need to find a balance between the opening and closing element, in general I wrote the code, but the problem is that I can receive the same opening and closing element, how can I check it, it turns out that both the opening and closing elements go to the stack.
  For example, what comes as a string argument '| () |' or '111115611111111222288888822225577877778775555666677777777776622222' '
  
  

  вот даны пары :
  const config1 = [['(', ')']];
  const config2 = [['(', ')'], ['[', ']']];
  const config3 = [['(', ')'], ['[', ']'], ['{', '}']];
  const config4 = [['|', '|']];
  const config5 = [['(', ')'], ['|', '|']];
  const config6 = [['1', '2'], ['3', '4'], ['5', '6'], ['7', '7'], ['8', '8']];
  const config7 = [['(', ')'], ['[', ']'], ['{', '}'], ['|', '|']];
  
  сам мой код :
  function check(arr, bracketsConfig) {
    let strArr  = bracketsConfig;
    let open = [];
    let close = [];
    let stack = [];
  
     for (var i = 0;i<strArr.length;i++){
          open.push(strArr[i][0])
          close.push(strArr[i][1])
     }
  
       for (let j = 0; j<arr.length; j++){
           if(open.includes(arr[j])&& !close.includes(arr[j]) ){
               stack.push(arr[j])
          }else{
              if(close.indexOf(arr[j]) === open.indexOf( stack[stack.length-1] )){
                  let p = stack.pop()
                  console.log(close.includes(p))
              }else{
                  return false
              }
          }
      }
          return stack.length === 0
   }
