[jquery] JavaScript console.log causes error: "Synchronous XMLHttpRequest on the main thread is deprecated..."

The question raised in 2014 and it's 2019 so I guess it's good to look for better option.

You can simply use fetch api in Javascript which provide you more flexibility.

for example, see this code

fetch('./api/some.json')
    .then((response) => {
        response.json().then((data) => { 
            ... 
        });
    })
    .catch((err) => { ... });
