I have large amount of data that i want insert it into indexedDB database.
The size of data about 5MB.
And more than 77,000 row.

const AllData = [
{ id: 1, en: "10th", ar: "arabic word" },
{ id: 2, en: "1st", ar: "arabic word" },
{ id: 3, en: "2nd", ar: "arabic word" },
{ id: 4, en: "3rd", ar: "arabic word" },
{ id: 5, en: "4th", ar: "arabic word" },
{ id: 6, en: "5th", ar: "arabic word" },
{ id: 7, en: "6th", ar: "arabic word" },
{ id: 8, en: "7th", ar: "arabic word" },
{ id: 9, en: "8th", ar: "arabic word" },

var db;
var request = window.indexedDB.open("YesData13", 1);
request.onerror = function(event) {
alert("Why didn't you allow my web app to use IndexedDB?!");
};
request.onsuccess = function(event) {
db = event.target.result;
/*
var transaction = db.transaction(["data"], "readwrite");
transaction.oncomplete = function(event) {
alert("All done!");
};
transaction.onerror = function(event) {
// Don't forget to handle errors!
};
var objectStore = transaction.objectStore("data");
for (var i in AllData) {
var request = objectStore.add(AllData[i]);
request.onsuccess = function(event) {
// event.target.result == customerData[i].ssn;
