hashmap
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Gojq: Pure Go Implementation of Jq
Why use a special syntax that's hard to remember when you can just use Python?
I wrote a jq-like that accepts Python syntax called pq: https://github.com/dvolk/pq
So you can write stuff like:
$ echo '{ "US": 3, "China": 12, "UK": 1 }' | pq -c "sum(data.values())" -
FX: An interactive alternative to jq to process JSON
If you want to use jq but with Python syntax, I wrote pq:

SwissMap: A smaller, faster Golang Hash Table
I generally just use this one: https://github.com/cornelk/hashmap
Mostly in that it also gives me lock free performance, which cleans up a lot of defers.

Go 1.20 Released
Glad to see this make it into the core.
I've been using this library for ages now...
https://github.com/cornelk/hashmap
Always entertains me to see developers write all the lock/unlock code when they could just use that.

HaxMap, a concurrent hashmap faster and more memory-efficient than golang's sync.Map
Pre-allocating would not fix https://github.com/cornelk/hashmap/issues/47 as the bug is in the linked list. This is not grow related but an issue with concurrent Add/Delete on the list.

A Go implementation of the concurrency control algorithm in paper <Left-Right -A Concurrency Control Technique with Wait-Free Population Oblivious Reads>
Would be interesting to compare with https://github.com/cornelk/hashmap

how does lock-free (or lockless) hashmap works?
I ran across this library recently - https://github.com/cornelk/hashmap
What are some alternatives?
gofx - 🐾 fx-like command-line JSON processing tool
haxmap - Fastest and most memory efficient golang concurrent hashmap
query-json - Faster, simpler and more portable implementation of `jq` in Reason
