How to get the percentage of total items in an array that have been processed in a loop?
Example:

var arr = ["AF","AL","DZ","AS","AD","AO","AQ","AG","AR","AM","AW","AU","AT","AZ","BS","BH","BD","BB","BY","BE","BZ","BJ","BM","BT","BO","BA","BW","BV","BR","IO","BN","BG","BF","BI","KH","CM","CA","CV","KY","CF","TD","CL","CN","CX","CC","CO","KM","CG","CD","CK","CR","CI","HR","CU","CY","CZ","DK","DJ","DM","DO","EC","EG","SV","GQ","ER","EE","ET","FK","FO","FJ","FI","FR","GF","PF","TF","GA","GM","GE","DE","GH","GI","GR","GL","GD","GP","GU","GT","GN","GW","GY","HT","HM","HN","HK","HU","IS","IN","ID","IR","IQ","IE","IL","IT","JM","JP","JO","KZ","KE","KI","KP","KR","KW","KG","LA","LV","LB","LS","LR","LY","LI","LT","LU","MO","MK","MG","MW","MY","MV","ML","MT","MH","MQ","MR","MU","YT","MX","FM","MD","MC","MN","ME","MS","MA","MZ","MM","NA","NR","NP","NL","AN","NC","NZ","NI","NE","NG","NU","NF","MP","NO","OM","PK","PW","PS","PA","PG","PY","PE","PH","PN","PL","PT","PR","QA","RE","RO","RU","RW","SH","KN","LC","PM","VC","WS","SM","ST","SA","SN","RS","SC","SL","SG","SK","SI","SB","SO","ZA","GS","ES","LK","SD","SR","SJ","SZ","SE","CH","SY","TW","TJ","TZ","TH","TL","TG","TK","TO","TT","TN","TR","TM","TC","TV","UG","UA","AE","GB","US","UM","UY","UZ","VU","VE","VN","VG","VI","WF","EH","YE","ZM","ZW"];
//
var per = arr.length / 100;
var count = 0;
// loop
for (var i = 0; i < arr.length; i++) {
count++;
// console.log(per * count - arr.length); // output 328.43999999999994
}
But if the intention is to show the progress in the browser, then complicates.
