Moving arrays to another object?

Hey guys,

I'm just starting out in Javascript and I was trying to do two simple exercises.

The first one takes an array and produces a new inverted one:

function reverseArray(input) {
var newArray=[];
for (var i=input.length-1; i>-1; i--) {
newArray.push(input[i]);
}
return newArray;
}

console.log(reverseArray(["A", "B", "C"]));
// → ["C", "B", "A"];

The second one inverts the variable itself:

function reverseArray(input) {
var newArray=[];
var originalLength=input.length;
for (var i=input.length-1; i>-1; i--) {
input.push(input[i]);
}
for (var i=0; i<originalLength; i++) {
input.shift();
}
return input;
}

var arrayValue = [1, 2, 3, 4, 5, 6, 7];
reverseArray(arrayValue);
console.log(arrayValue);
// [7, 6, 5, 4....

It's working, but isn't there a simple way to just move the array to another variable? If I just take the first exercise and print in the last line input=newarray, the array doesn't move to the input variable.


Thanks a lot in advance guys
