2:24 why we use let instead of var ?

I'm aware of using var and let but the position of the enemy could change while playing the game so i thought this could be var instead ! that confuse me more when using let over var in mutable data type !

Hi Jeff,

I believe Pasan says at some point earlier that enemies will be in a fixed position in the game, so it makes sense for the position to be a constant.

Great question, though! Glad you're thinking about this stuff.

Cheers :beers:
