Welcome!

layout packages by what they do, not by their abstract type
use channels sparingly: write synchronous methods and allow the caller to make it async
append modifies the underlying slice, you’ll only make this mistake once
define interfaces where you use them
make([]int, 5) has a length and capacity of 5. ([]int, 0,5) has a length of 0 and capacity of 5.
append() will only do what you want with the latter
don’t use init()
TFBO (test, fix, benchmark, optimise)
more CPU != more performance
more CPU == more contention
