The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

TySON: TypeScript as an embeddable configuration language, without depending on Node or V8
Apparently "not depending on Node or V8" means depending on some random Go JS engine instead.

Running a Js file inside Go
Either call a JavaScript interpreter like node with exec.Command and read its stdout, or use a pure Go JavaScript interpreter like goja or otto.

easytemplate - Go's text/template library with JS Super Powers
Just to also say this is implemented in pure Go we aren't including V8 or any external dependencies we instead use https://github.com/dop251/goja which is a JS VM written completely in Go.

Anyone experienced in golang ssr?
Not really. It was built in-house and I don't know of anything about it that went public. I recall it using Goja for the JS runtime. Code was embedded into the binary (think embed package). There was some kind of sorcery to convert what would be HTTP network calls in the browser into local function calls during SSR, but I'm hazy on how it worked I'm afraid.

Plugo - A plugin library for Go.
Other approaches I've seen are similar to yaegi but will embed another scripting language such as JavaScript or Lua. My personal favorite of these is goja, a JavaScript interpreter written natively in Go (no cgo dependency), it supports a lot of ES6+ modern syntax features of JavaScript. Being natively in Go, you can bind your Go functions and types and call them bidirectionally, so you can expose a surface area of internal API functions to your JS interpreter and build a scripting system for users to extend your app dynamically.

Run single JS func in Go app
Where are your benchmarks showing github.com/dop251/goja, v8go and otto are slow? by my own testing they are sufficiently fast enough.

Change go code behaviour at runtime
For JavaScript syntax, https://github.com/dop251/goja is the most mature and featureful. It operates between Go and the scripting engine pretty well. They still need to implement generators before moving on to async/await and proper module support, but they have a lot of other advanced es6 level features such as classes and format strings. There are soem big consumers of this--the biggest might be Grafana K6, or at least they contribute back a bit. Most of the work (like many small projects) comes from one guy that has a real job, but he's slowly yet steadily made improvements and stuck to following standards for many years now.
What are some alternatives?
When comparing anko and goja you can also consider the following projects:
otto - A JavaScript interpreter in Go (golang)
v8go - Execute JavaScript from Go
go-lua - A Lua VM in Go
gopher-lua - GopherLua: VM and compiler for Lua in Go
tengo - A fast script language for Go
go-python - naive go bindings to the CPython2 C-API
go-duktape - [abandoned] Duktape JavaScript engine bindings for Go
gval - Expression evaluation in golang
