like below fixes the issue If you're using jQuery: $.parseJSON().
If you're using plain javascript: JSON.parse()

code :

// jQuery snipet
var thumbnails = $.parseJSON('<?php echo $thumbnails; ?>');
console.log(thumbnails.src);
console.log(thumbnails.width);
console.log(thumbnails.height);

Unable to parse json encoded values from php into JSON parse in javascript/jquery

this one helps. Turns out the problem was within the server side of the script so I amended my code based on your suggestions and this is what I arrived with that works for me.

code :

function display($dbhandler){

    $sql = "SELECT * FROM users";
    $result = array();
    foreach($dbhandler->query($sql) as $row){
        $data = array('id'=>$row['id'], 
                         'email'=> $row['email'], 
                         'name'=> $row['name']
                         );

        array_push($result,$data);      

    }

    echo json_encode($result);

}

How to parse svg polyline data from url using JSON.parse() in JavaScript?

I think the issue was by ths following , There are various problems with your code, like defining url twice. You probably want to use the fetch API to get it. You'll have to run your code on colorillo.com or rehost the file on your own server, because they haven't set up CORS to allow you to access the file from another website.
SVG is a dialect of XML, not JSON. You need to use a DOMParser:

code :

// Create request to fetch the SVG file.
xhr=new XMLHttpRequest();
// Tell the request where the file is.
xhr.open("GET", "http://colorillo.com/bxys.inline.svg");
// Add event handler to process the file once it's been fetched.
xhr.addEventListener("load", function() {
  // Once the text is available, create an XML parser
  // and parse the text as an SVG image.
  const xmlDoc = new DOMParser().parseFromString(
    this.responseText.trim(), 
    "image/svg+xml"
  );
  // xmlDoc.getElements() returns something Array-like, but not an Array.
  // This turns it into an Array.
  const polylines = Array.from(xmlDoc.getElementsByTagName('polyline'));
  console.log(polylines.map(
    pl => [
      // Parses each 'points' attribute into an array of pairs of numbers
      pl.getAttribute('points').split(' ').map(
        pair => pair.split(',').map(x=>+x)
      ),
      // Various stroke information

      // Convert rgb(R,G,B) to #RRGGBB
      // Leading hash, then pull out the digits with a regex
      '#' + pl.style.stroke.match(/rgb\((\d*), (\d*), (\d*)\)/)
        // Throw away everything but the digits
        .slice(1,4)
        // Convert to a number, render in hex, uppercase, pad with 0s
        .map(x=>(+x).toString(16).toUpperCase().padStart(2,'0'))
        // Concatenate the hex digits
        .join(''),
      +pl.style.strokeWidth,
      pl.style.strokeLinejoin,
      pl.style.strokeLinecap
    ]
  ));
});
xhr.send();

$JSON from python json.dumps to javascript JSON.parse() with escaped \"$

JSON from python json.dumps to javascript JSON.parse() with escaped \"

To fix the issue you can do In order to put a string of JSON into JavaScript source code, you used backticks to make it a template string. That’s not enough, though, since many sequences have special meaning inside backticks:
${…} interpolation backslash escape sequences (the current problem, which converted the \" in the JSON to ") backticks

code :

def script_embeddable_json(value):
    return (
        json.dumps(json.dumps(value))
        .replace("<", "\\u003c")
        .replace("\u2028", "\\u2028")
        .replace("\u2029", "\\u2029"))


json_js = script_embeddable_json(dic)
