pigeon is a Go library typically used in Utilities, Parser applications. pigeon has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The pigeon command generates parsers based on a parsing expression grammar (PEG). Its grammar and syntax is inspired by the PEG.js project, while the implementation is loosely based on the parsing expression grammar for C# 3.0 article. It parses Unicode text encoded in UTF-8. See the godoc page for detailed usage. Also have a look at the Pigeon Wiki for additional information about Pigeon and PEG in general.

            Answered 2021-Oct-24 at 03:44

            I played around with the code for a bit and got something that worked. My initial suggestion is going to be that you shouldn't try doing left and right with vanilla javaScript and the up and down with jQuery. I used jQuery to get this to work, but it can certainly be done with vanilla javaScript as well.

            The first thing that I did was make a global variable n that keeps track of our position in the grid, so when you press the left or right arrow it either adds 1 or subtracts 1 from n, and up and down arrows either adds or subtracts 25.

            For each of our little if statements I've made them a bit more generic. First it selects the current div that the player is in, and using the .html() function in jQuery grabs the HTML (as a string) which we can then use. I noticed that in your initial code when you were trying to add the player variable with .append() you got an error about string literals. Since the selection of player was a jQuery object it wasn't able to append that since .append() takes in a string (aka "Hello, World!"). Secondly, when we get the response from .html() (which is a string), we are then able to append it to a new position in the grid. Doing this means we're moving positions so n needs to be changed as I stated above. Note that I also used .empty() to clear the player from the previous block. Finally, we can append player which would look something like

            Bottom line of those SOLID principles, is to make the code more understandable, easy to maintain, and easy to scale.

            Each solution would work, but think, does it make sense for your code to split those behaviors into two different interfaces?

            Or maybe it would be better to create these interfaces:
