> It lacks simple things like check if a key exists in a map.
What? `value, keyExists := myMap[someKey]`
> Try removing an element from an array - you must rely on some magic and awkward syntax, and there's no clear explanation what actually happens under the hood (all docs just show you that a slice is a pointer to a piece of vector).
First of all, if you're removing elements from the middle of an array, you're using the wrong data structure 99% of the time. If you're doing that in a loop, you're hitting degenerate performance.
It has iterators - https://pkg.go.dev/iter.
