My 15-year-old self would be shocked at my day-to-day as an engineer now.
I -would- definitely like more in the standard data structures and algos realm. I used to be more active on golang-nuts, and a lot of the replies to such ideas was "it's so easy to write yourself, look at this 5 liner, why make a package for it." Initially I kinda understood, but years in, after rewriting the same things over and over, it would be nice to one line a lot of this.
It's been widely considered as a mistake for about two decades now...
> I couldn't even find a standard linked list.
Even? If you need a linked list, then you have a 0.01% use case and shouldn't expect such a niche data structure to be easily available. That said, https://pkg.go.dev/container/list
> What if I have a list where I need to make lots of insertions in the middle?
Then you should use an array. If you're not making full use of the pointer-y nature of a linked list, you shouldn't be using it.
> Where is the data structures package?
Go only got generics in 2022 so the standard library is lacking in ergonomic data structures.
When I first encountered Go, I was still a learner and the lack of these things in the language and standard libraries shocked me. But it turns out that they were writing a language more for practical software engineering than for outdated curricula. At the end of the day, structs, slices, and maps cover 99% of what you need!
