parse (input) to JSON string

Question

Hello not overly familiar with JavaScript quite new to it actually so i pulled bits from other projects and now struggling to wrap things up.

This is for a small RGB lighting project. The json payload message is transported via MQTT and the initial input is a string value as follows "rrr,ggg,bbb".

what i have come up with so far is as follows

(function(i) {

  var rgb = i.split(",");
  var color = {"r":rgb[0],"g":rgb[1],"b":rgb[2]}
  return JSON.stringify({color});

})(input)

Desired result needs to be {"color":{"r":232,"g":200,"b":55}}

the JS gets stored as a .js file and referenced when transformation is needed

any help would be much appreciated.

Are you getting an error? What is not working? What kind of help are you looking for? — willman

It appears you are creating your inner object correctly, but the value you are stringifying is just the inner object wrapped in braces, you need to change your stringify line to:

 return JSON.stringify({"color": color});

The way you currently have it written, would come out as

{{"r":232,"g":200,"b":55}}
