Answer 4

just turn out "x.name" to "a[x].name" or use the for..of loop:
for (let x of a){
alert(x.name)
}

Answer 5

Just change this:
for (let x in a){
to this:
for(let x of a){

in other words, change 'in' to 'of'.

Answer 6

function Person(name, ...correct){
this.name=name
this.correct=correct
}
var a = [
new Person("Hi",7,1,2,3),
new Person("Bye",1,3,4,2)];
for (let x of a){
alert(x.name)

result
Hi on first window
Bye on second window
