The visitor pattern is a way of getting multiple dispatch in a language with single dispatch.
It can also be seen as a way of encoding a functional solution to the expression problem in an OO language, which is useful when you have a set of objects and want to make it easy to add new operations to them, not create new types of objects.

I'm a software engineer with two decades of commercial experience. I've helped startups get started and big companies keep going.
I've organised a couple of jobs through HN now; it's been a good way to find interesting projects, and my clients have been pleased with the work. One said: "Thank you! I've played with it a bit and it looks very impressive! Way better than what I imagined this project could be."
I've worked on a very wide variety of web-based projects, as well as React Native, Windows, and other platforms, so I will be able to hit the ground running on most projects. If you're doing something a bit esoteric, that could still suit me – I've done image analysis of microscope images, processing big data for satellite imagery, devised novel algorithms, written network protocols, hacked on FPGAs, basically a bit of everything.
I did a PhD in programming languages so I'm pretty good at picking them up. In the last 5 years I've done commercial projects in (at least):
Typescript/Javascript (React Native, browser, and Node.js), C#, Python, Java, Swift, Ruby and Golang. I'm trying to find someone to pay me to do some Rust (I completed an Advent of Code in it.)
As well as building things, I am also good at talking to people to help figure out what we should be building. I enjoy working with other developers and helping the team learn, but I am also happy to get my head down and build what you need. I'm happiest on fixed-term projects that I can complete on a schedule that suits both of us, and my clients have been very happy with this process too.
Hypothecated taxes are an anti-pattern, for precisely this reason. Setting the budget and setting the taxes should be somewhat separated (but not too separated!)
To be fair, that's one of the reasons why libraries like jQuery and React exist: to smooth over the difference between browsers.
Even today, big chunk of React is masking the subtle differences in event handling and other things. And whilst it forces you into a paradigm, I've never had a bug caused by the internals of React that I've had to dig into. But maybe I'm lucky or only do simple stuff?
As to it hurting, I guess I'd say, use the protective equipment! Sure, it can be bulky and awkward occasionally, but it works and it's often better than the alternatives.
This sounds exciting but the enormous and confusing breadth of what your bio says you are working on, and the odd unit errors (lowering "a megawatt" to "2 to 3 terawatt), is really harming you credibility here. Do you have a link to a well-explained example of what you've achieved so far?
