@ -446,13 +446,13 @@ then a sixteen-slots array. And in a couple more calls to ~realloc~,
we’ll quickly reach our tens of thousands slots array, way faster than
by incrementing its capacity one by one.

You’re completely right, but that’s a tradeoff. Would you rather have
a slow but memory-efficient program, or a fast but memory-hungry
software? Plus, as you’ll see later, there is a function to shrink the
size of the allocated array down to the actual amount of elements you
stored in it, making it possible to temporarily have a 2^{32} elements
stored in it, making it possible to temporarily have a 2^{17} elements
array, and immediately after shrink it down to 2^{16}+1, once you know
you won’t be adding any other elements.
