@alexisabril Are you guys storing the video tutorials somewhere, so that we can revisit them? I usually miss the first part :(

@niceindividual
kinda reminds me of the index on a hard drive
Alexis Abril
@alexisabril
Similar logic! If you’ve ever done any assembler development, this would look very familiar
Shouldn't c be under the 5 instead of the 2?
cool
Alexis Abril
@alexisabril
@Madelene you’re correct, it was a typo but moving the c would’ve also fixed the example
got it :) Thanks :)
Alexis Abril
@alexisabril
typo with writing…write-o? :)
ha
(sounds british)

@omarmeky
Wouldn't looking up a VALUE still be O(n) here?
Just to clarify: because n never gets too big, this will make our code run faster, yes?
faster= more efficient
got it!
(thanks) :)

In your name example does name="alexis" create a new variable? So me is a variable with a property and name is a new var?
Alexis Abril
@alexisabril

Yes, name would be a new variable in that scenario. We used the shorthand syntax so it was something akin to:

var me = {}, name = {}

or name = “alexis”
“name” itself, is a new variable in memory which points to whatever is declared to the right of the “="
Sonju
@Sonju
Pronunciation is correct!
John Hitz
@johnhitz
And in me.name, name is a property of me???
Thanks!
Russell Smith

Thanks for this one guys. I finally have an understanding of why hash maps are quicker than arrays.
