Wasm 1.0 did not include garbage collection, but there is a lot of effort right now by many people to add it (that is what I work on myself currently). Once wasm has GC, languages like Grain will be able to save a lot on code size, and have some advantages over the "first set" of wasm languages (C/C++/Rust/Zig/etc., all using linear memory), like smaller sizes, less memory fragmentation, and properly collecting cycles with JS.
