Question: ```
    app.post(' /', urlencodedParser, function(req, res) {
      res.render('load', {data: req.body});
      var token = req.body.token;
      require('./loader.js')
    });

```

How can I provide variable "token" to loader.js?

Answer: 
Hell yeah!! I'm very happy to finally reach to the solution myself using some of the hints given to me here:

```js
function validBraces(braces){
    let opening = [ '(', '[', '{']
    let closing = [ ')', ']', '}']
    let arr = []
    //console.log(closing.indexOf(braces[")"]) === opening.indexOf(arr[")"]))
    for (let i = 0; i < braces.length; i++) {
        if (opening.includes(braces[i])) {
            arr.push(braces[i])
        } else
        if (closing.indexOf(braces[i]) === opening.indexOf(arr[arr.length - 1])) {
            arr.pop()
        } else return false
    } return arr.length === 0;
}
```

I was clearly overthinking it in the first place haha. Thanks for everyone that helped!
```
function validBraces(braces){
    let par =0;
    let bra =0;
    let cur =0;
    for(let i =0; i<braces.length; i++){
        if(braces[i]==="("){
            par++;
        }
        if(braces[i]===")"){
            par--;
        }
        if(braces[i]==="["){
            bra++;
        }
        if(braces[i]==="]"){
            bra--;
        }
        if(braces[i]==="{"){
            cur++;
        }
        if(braces[i]==="}"){
            cur--;
        }
    }

    if(par<0 || bra<0 || cur<0){
        return false;
    } 
    return true;
};

```
