Download response.data as a file, through Blob()
// 'downloadFile.js', written by blending two solutions:
// 'js-download' https://github.com/kennethjiang/js-file-download
// 'Anders Paulsen' https://blog.jayway.com/2017/07/13/open-pdf-downloaded-api-javascript/
export function downloadFile(data, filename, mime) {
// It is necessary to create a new blob object with mime-type explicitly set
// otherwise only Chrome works like it should
const blob = new Blob([data], {type: mime || 'application/octet-stream'});
if (typeof window.navigator.msSaveBlob !== 'undefined') {
// IE doesn't allow using a blob object directly as link href.

deleting array items in javascript with forEach() and splice()
// This is from my comment here: http://wolfram.kriesing.de/blog/index.php/2008/javascript-remove-element-from-array/comment-page-2#comment-466561
/*
* How to delete items from an Array in JavaScript, an exhaustive guide

// DON'T use the delete operator, it leaves a hole in the array:
var arr = [4, 5, 6];
delete arr[1]; // arr now: [4, undefined, 6]
