Solving the Expression Problem in Go
Not diminishing the article at all, there's massive value I've gained from leveraging this runtime solution in multiple projects: https://github.com/antonmedv/expr
The language is easy enough for people to pick-up.
- Expr Release v1.15
- Expr v1.14 release: Go expression language
- Expr – expression language with type checker

FireScroll - The config database to deploy everywhere (now with conditional statements!)
Uses the [expr](https://github.com/antonmedv/expr) language to achieve this and I've been super happy with the results.

Library to analyze an arbitrary JSON string
I have been using expr (https://github.com/antonmedv/expr) to do something like this for a while. no complains so far.

[gcalc] A simple calculater in golang
If you wanted it to not require putting in the operation first and just accept string equations (without using something like https://github.com/antonmedv/expr) you could parse, tokenize and then process the input.

Suggestion for a dynamic Struct Validation Rules
https://github.com/go-ozzo/ozzo-validation Seems to do what I need but likely will need some convoluted reflection to build out the rules. Also likely some custom rules to be written which is okay since it's a one time cost and reuse in the expressions.

Proper validation package suggestion
Personally I use ozzo validation: https://github.com/go-ozzo/ozzo-validation

Valgo is a type-safe, expressive, and extensible validator library for Golang.
This looks useful, but what differentiates it from something like https://github.com/go-ozzo/ozzo-validation ? Why would I use Valgo over something battle tested that follows a very similar pattern?

Why use go over node?
This is where it gets spicy: I just don't get at all who ever though this struct-tag based validation library was a good idea https://github.com/go-playground/validator - and yet it's the most mainstream one. Try to implement your own type, you're up to register some global validation tag and repeat it every time you're using that type. I'm grateful https://github.com/go-ozzo/ozzo-validation exists, that's what I use. But it's still way behind the other things I mention, where in general, it's simply not possible to pass around an invalid struct - because it can't be built if it's invalid in the first place.

Gin vs Echo framework
Gin comes with built-in "validation", while Echo recommends the same validator. I am also not a fan of magic struct tags, so I would probably prefer either writing my own or using something like ozzo.
