When working with Arrays, isn't push and length identical ? If so why do I see length property used most frequently ? I personally am growing use to using push, was a little easier for me to remember. In my discoveries I find the length property used instead.
What is the following mean;
one[one.length-1] ?
I know one[one.length] will add to the end of the array, what is -1 doing to the array ? Can you do +2, -2, +4 etc to the length property ?
