In some parts of the code there is a space on either side of =
ex: var = friendNumber = 1
but later, there are no space
ex: for(var i=0; i < 4; i+=1)
Is there a reason for this? Is it significant?
Thanks

Whitespace is just for us humans so we can read the code easier. Both of these var declarations are valid:
var a = 1;
var a=1;
However keep in mind that sometimes white space is required. This would not be valid:
vara=1;
You need a space between a javascript keyword and its variable name. It works the same in loops:
for(var i = 0; i < 4; i++)
for(var i=0; i<4; i++)
So the short answer: its all about preference. Whitespace makes the codes more readable and its not always required.
