Javascript map CSV string to JSON array

this one baffles me and I'm not even sure I'm searching the correct keywords for possible explanations.

I am sending an RPC to a remote server. The response I get is just a comma-delimited string with values (no keys) like so:

val1,val2,val3,val4,val5,val6,val7,val8,val9

When I receive this response I need to map these values through JS to keys (hard-coded, I designate) and generate a JSON array like this:

{
  "response": {
    "mykey1" : "val1",
    "mykey2" : "val2",
    "mykey3" : "val3",
    "mykey4" : "val4",
    "mykey5" : "val5",
    "mykey6" : "val6",
    "mykey7" : "val7",
    "mykey8" : "val8",
    "mykey9" : "val9"
  }
}

Can anybody nudge me in the right direction...sample code or tutorials that are close to what I am looking for? This is a for middleware script that gets called when server receives the response.

This is my first post here, been looking a long time learning and applying in Obj-C and as I am learning Swift, but JS is new to me. I apologize in advance if I am breaking any protocols by asking for help without posting my feeble attempts at figuring this out...

Solution

    1. You can split the response on comma, which will give you an array.

    2. Since both arrays (keys and vals) are the same length, you can loop over either and create your array of objects that way. See below 

    var response = 'val1,val2,val3,val4,val5';
var keys = [
  'key1', 'key2', 'key3', 'key4', 'key5'
];

var dict = [];
var vals = response.split(',');

vals.forEach(function(val, i) {
  dict[keys[i]] = val;
});

console.log(dict);
