How do we get string values from javascript object?

Question

I have javascript objects like:

{["186,2017"]}

I would like to only have:

186, 2017

I tried (thougth i had a json):

console.log(JSON.stringify(data));

But that is what gives me the json and not the string values only,

This is how I get the whoel thing:

$("#years").slider({
      tooltip: 'always',
      tooltip_position:'left',
      formatter: function(value) {
        currentRange = value instanceof Array ? value.join('-'): value;
        return 'Years: ' + (value instanceof Array ? value.join('-'): value);
        console.log(value instanceof Array ? value.join(', '): value);
      }
    });

    getData = function() {
      var data = {
          years: $('#years').slider().val().split(', ')
      }  
      console.log(JSON.stringify(data));
    }

    $("#years").on("slide", function(slideEvt) {
      getData();
    });

{["186,2017"]} is not valid JSON - if the JSON is ["186,2017"] ... JSON.parse(json).map(Number) - though, that would result in [186,2017] ... because you still have an array ... so, perhaps ... JSON.parse(json).join(", ") - in the above , json is the JSON string that "you have" ... if what you have is an array, data .. then you just want data.join(', ') — Jaromanda X

@JaromandaX I have updated the question, that format is what I get when I use stringify — rob.m

right, so you don't have JSON at all you have data = {years: ["186", "2017"]} — Jaromanda X

let obj = { years: ["186", "2017"] }

console.log(...obj.years);

You can try to spread it as above

but that won't split the elements by ", " just "," :p

I gather the object you are dealing with is a variable called data with the content {years: ["186", "2017"]}

to "get" the value "186, 2017" from that data

data.years.join(", ");
