Answer 1

If you want to acces a variable outside a function, make it global.

var variableOne = [
"newVarone",
"newVartwo",
"newVarthree",
1000
];

var variableTwo = new Var();
variable[0] = "newVarone";
variable[1] = "newVartwo";
variable[2] = "newVarthree";
variable[3] = 1000;

var variableThree;

function() {
console.log(variableOne[1]);
console.log(variableTwo[2]);
console.log(variableThree = "newVar");
}

Hope it helps👍
