JavaScript blob filename without link

Question

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

function newFile(data) {
    var json = J

Late, but since I had the same problem I add my solution:

function newFile(data, fileName) {
    var json = JSON.stringify(data);
    //IE11 support
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        let blob = new Blob([json], {type: "application/json"});
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    } else {// other browsers
        let file = new File([json], fileName, {type: "application/json"});
        let exportUrl = URL.createObjectURL(file);
        window.location.assign(exportUrl);
        URL.revokeObjectURL(exportUrl);
    }
}
