Perl in WebAssembly
Perl (Practical Extraction and Reporting Language) was the lingua franca of the early web. A powerful scripting language, it became a popular way to write CGI.
Larry Wall, its creator, once called it the “first post-modern programming language” because it was driven more by a desire to add the things developers liked than to follow specific academic strictures. Its regular expressions have lived on, influencing the designs of countless other programming languages.
There is no official Perl distribution that is WebAssembly-capable.
The WebPerl project provides a browser-centered Perl interpreter in Wasm. Build instructions support Perl 5.26 and newer.
WebPerl does not provide a WASI implementation, and does not appear to be runnable outside of a browser.
WebPerl describes usage inside of a browser.

- There is even a sample IDE
Things we’re not big fans of:
