Episode 1: discussed design and purpose of the programming language, implemented the parser for variable assignment and function call syntax. (commit)
Episode 2: implemented built-in runtime functions and user-defined functions. (commit)
Episode 3: wrote a run script to conviniently execute programs in the X language. Implemented code blocks which are similar to anonymous function expressions in JS, and use that and a runtime $if function to implement conditionals instead of an if statement. (commit)
Episode 4: implemented array literals, each, map, filter and reduce functions and added parameters to code blocks. (commit)
Episode 5: implemented implicit returns and tags for collection types. (commit)
Episode 6: implemented dictionaries. (commit)
Episode 7: implemented proper if statements and talked about the dangling else problem. (commit)
Episode 8: code clean up, string runtime functions, fixed if statement bug, did a code challenge.(commit)

The project depends on this libraries:

Also see my course How to Make a Programming Language for more detailed coverage of the topics encountered in this series.

index notation syntax
operators
classes
Unicode support (use different languages and emojis for var names)
Add enough feature to be able to solve some code challenges and do the word summary program
Clojure style protocols
FS support
DOM support
native if statement (done)
