JavaScript blob filename without link

by

How do you set the name of a blob file in JavaScript when force downloading it through window.location?

function newFile(data) {
    var json = JSON.stringify(data);
    var blob = new Blob([json], {type: "octet/stream"});
    var url  = window.URL.createObjectURL(blob);
    window.location.assign(url);
}

Running the above code downloads a file instantly without a page refresh that looks like:

I want to set the filename as my-download.json instead.
