How do you start your own programming language?
Here's a javascript library that lets you generate your own language that compiles to Javascript. https://pegjs.org/ It's a compiler generator. You can either use the command line tool and feed it your grammar (You have to write that) and use the generated parser.js which can then run your program, or use peg.js as a dependency and generate your parser at run time before feeding it your program.

Creating a custom parser with PEGJS
The PEG.js project got taken over by a new maintainer who locked everyone else out, never shipped a release, and then ignored repeated requests to transfer the project back to the community. So the community forked it to a new project - Peggy, which is where ongoing development happens: https://github.com/peggyjs/peggy

How to make your own programming language in JavaScript
NOTE: The original PEG.js project is not maintained anymore, but there is a new fork, Peggy that is maintained and it's backward compatible with PEG.js so it will be easy to switch.

Show HN: DTL: a language and JavaScript lib to transform and manipulate data
Thanks. Yes, DTL's core textual syntax is described with PEG. I make use of the Peggy (https://peggyjs.org/) PEG processor to build up the AST that is used to actually process DTL.
There are C based PEG processors, which I've looked at once or twice also, but I haven't sat down to try to convert it. Mostly out of a desire to get the existing module to work well. A working module for one language is better than a partially working module for multiple. :P
