Suppose we have following situation
$('#dom1').remove();
$('#dom2').remove();
$('#dom3').remove();
$('#dom4').remove();

So, we can write unit test as follows:

this.removeStub = sinon.stub($.fn, 'remove');
it('Should remove dom', function(){

# Manual construction of arrays

# one dimension array

array[start:end:step] # start through not past end, by step

start: the beginning index of the slice, it will include the element at this index unless it is the same as end, defaults to 0, i.e. the first index. 
If it's negative, it means to start n items from the end.

end: the ending index of the slice, it does not include the element at this index, 
defaults to length of the sequence being sliced, that is, up to and including the end.

step: the amount by which the index increases, defaults to 1. If it's negative, you're slicing over the iterable in reverse.
