let s = '([]{})()'

const isValid = function(s) {
    let stack = []
    let characters = '()[]{}'   // even, odd, even, odd, even, odd

    for (let i = 0; i < s.length; i++) {
        let index = characters.indexOf(s[i])

        if (index % 2 === 0) {
            stack.push(s[i])
        } else if (index % 2 !== 0 && stack[stack.length - 1] === characters[index - 1]) {
            stack.pop()
        } else {
            return false
        }

        console.log(stack)
    }

    return !stack.length
}


console.log(isValid(s))

// [Log]:
[ '(' ]
[ '(', '[' ]
