Old $.ajax() request

oldajax.js

$.ajax({
    data: someData,
    dataType: 'json',
    url: '/path/to/script',
    success: function(data, textStatus, jqXHR) {
        // When AJAX call is successfuly
        console.log('AJAX call successful.');
        console.log(data);
    },
    error: function(jqXHR, textStatus, errorThrown) {
        // When AJAX call has failed
        console.log('AJAX call failed.');
        console.log(textStatus + ': ' + errorThrown);
    },
    complete: function() {
        // When AJAX call is complete, will fire upon success or when error is thrown
        console.log('AJAX call completed');
    };
});

There is a problem with
complete: function() { // When AJAX call is complete, will fire upon success or when error is thrown console.log('AJAX call completed'); };
You need to delete the ';' at the end of the function.
Thanks
