AJAX seems to be struggling to recognize JSON data as JSON format

I am facing an issue with my AJAX call where the data received from the server is not being treated as JSON, despite setting the datatype to json:

function RetrieveMateriasFromServer(callback){
    var status_aux;
//HTTP request for data from the given URL. If the received data is as expected, goes into the SUCCESS case
return $.ajax({
    url: 'materiasphp/materias.php',
dateType: 'json',
    success: function(data)
    {
        status_aux = data;
        callback(status_aux);
    var test = JSON.stringify(data);
    console.log(data);
    console.log(test[1]);
    }

The console prints test[1] = "["

It appears there is a mistake in your code. The correct statement should be dataType: instead of dateType:.

return $.ajax({
  url: 'materiasphp/materias.php',
  dataType: 'json',

var example = JSON.stringify(data);

It might be better to do

var example = JSON.parse(data);
// or simply 
var example = data;

This is because if you use stringify, then you will have to access characters in the string using bracket notation.

var word="dog";
console.log(word[0]);

The output is d, the first letter of the word.

JSON is a type of data format that is based on text.

When you use JSON.stringify(data);, it will take the variable data and convert it into a JSON text, which will then be stored in a string.

console.log(test[1]); will then access the character located at index 1 in that string and display it.

This behavior is considered standard.

If you prefer to work with the data as a JavaScript data structure, it is recommended to avoid converting it to JSON.

You can simply interact directly with the data structure contained in the data variable.
