How JavaScript saves text as a file in a browser

Tested the second way to save more text than to get stuck

var saveTextAsFile1 = function (text, FileName, success, error) {var data = text; if (! (    Text instanceof Array) {data = [text];    } var file = New file (data, fileName);    var reader = new FileReader ();    Reader.readasdataurl (file);        Reader.onload = function (r) {var url = reader.result;            DownLoadFile (URL, fileName, function () {Success && success ();            }, function () {Error && error ();    }); };} /** * Download File * @param {string, Array} text * @param {string} FileName * @param {function} success * @param {function} err    or */var savetextasfile = function (text, FileName, success, error) {var data = text; if (! (    Text instanceof Array) {data = [text]; } var urlobject = window. URL | | Window.webkiturl | |    Window    var export_blob = new blob (data);    var url = urlobject.createobjecturl (Export_blob);         DownLoadFile (URL, fileName, function () {   Success && success ();        }, function () {Error && error (); });}
