Script Preparation code:

var a = new Array(1000);
a.fill([1,2,3,4]);

var ia = Immutable.List(a);

Tests:

native
a.shift(); a.push([1,2,3,4]);
immutable array push
ia = ia.push([1,2,3,4]); /*var pia = ia.withMutations(function(mat){ mat.shift(); mat.push([1,2,3,4]); }); var nia = pia.toArray(); */
