Balanced Brackets

    Code passes all tests, but semantically does not match problem description:

    The pair of square brackets encloses a single, unbalanced opening bracket, (, and the pair of parentheses encloses a single, unbalanced closing square bracket, ].

    JavaScript:

    function isBalanced(s) {
    const missing = []
    s = [...s]
    for(let i = 0; i < s.length; i++) {
        const char = s[i]
        const nextChar = s[i+1]
        switch (char) {
            case "{":
                missing.push("}")
                break
            case "[":
                    missing.push("]")
                break
            case "(":
                missing.push(")")
                break
            case "]":
            case "}":
            case ")":
                if(missing.length === 0 || missing.pop() != char) 
                    return "NO"
                break
            default:
                return "NO"
        }
    }
    
    
    return missing.length > 0 ? "NO" : "YES"

}
