Reverse part of an array using javaScript

Question

I have an array in Javascript like so:

var v = new Array("a","b","c","d","e","f"...);

I would like to reverse it but keep the first two elements, so it would turn into:

"a","b",...."f","e","d","c"

How can I do this?

Answer 1

Try this way:

var v = new Array("a","b","c","d","e","f");
var newArr = v.splice(0,2).concat(v.reverse()); // get the first 2 out of the array
console.log(newArr);

• splice
• concat
• reverse

Answer 2

v = [].concat( v.slice(0,2), v.slice(2).reverse());
//v --> ["a", "b", "f", "e", "d", "c"]
