Js Arrays = Python Arrays, assignments to an array are references, not copies.

You need to create an entirely new array if you need to duplicate it(Shallow/Deep copy).

Tuples == Arrays, but immutable!

So, the similarity between Python an JS is that the strings are immutable in the two languages.

The Multiple Assignment Trick
The multiple assignment trick is a shortcut that lets you assign multiple vari-
ables with the values in a list in one line of code. So instead of doing this:
>>>
>>>
>>>
>>>
cat = ['fat', 'black', 'loud']
size = cat[0]
color = cat[1]
disposition = cat[2]
you could type this line of code:
>>> cat = ['fat', 'black', 'loud']
>>> size, color, disposition = cat

'in' and 'not in' operators
a = [1,2,3,4,5]
5 in a
>>>True
10 not in a
>>>True
