We encountered the following issues during the adaptation due to the differences between the Source languages and Scheme, and briefly sketch here how they are resolved in SICP JS.
The audience is welcome to inspect SICP JS by visiting https://source-academy.github.io/sicp. A comparison edition lets the reader inspect the changes and compare them line-by-line with the original. The presentation will leave ample time for discussion. Any email questions or suggestions are welcome prior to the presentation (mailto:firstname.lastname@example.org, email@example.com) and shall allow the presenters to prepare a more detailed response.
The presentation will also cover the Source Academy, an online learning environment for programming, developed by and for students at the National University of Singapore, which implements the four Source languages along with several variants and extensions introduced in SICP.
