}
for(let i of data) {
console.log(i)
}
for(let i in data) {
console.log(i)
console.log(data[i])

var index;
var a = ["a", "b", "c"];
for (index = 0; index < a.length; ++index) {

}
var key;
var a = [];
a[0] = "a";
a[10] = "b";
a[10000] = "c";
for (key in a) {
if (a.hasOwnProperty(key) &&
/^0$|^[1-9]\d*$/.test(key) &&
key <= 4294967294
) {
console.log(a[key]);
}
}
const a = ["a", "b", "c"];
for (const val of a) {
console.log(val);
}
const a = ["a", "b", "c"];
const it = a.values();
let entry;
while (!(entry = it.next()).done) {
console.log(entry.value);
}
