Array Mutations Observer

As we all know that the array is immutable in nature, so we cannot increase and decrease the size of the array, but in polymer Js we can do this by using the "Array Mutations Observer" concept to make the array mutable.

static get LFC(){
static get LFC(){
return[ 'changed(lfc.splices)' ]
\\contacts is an array which contains items
\\.splices makes an array mutable

If any change happen in the structure of an array, then changed() is callback function gets invoked
