WebAssembly is actually simple to work with. If you want to obtain a "C" pseudocode, you can give a wasm file to wasm2c [1]. You can re-obtain a WebAssembly folded-expression text format using wasm2wat [1]. You can obtain a call-graph from a WebAssembly module by generating the wat representation using wasm2wat and pasting it into main.wat on https://webassembly.studio/ https://webassembly.studio/ (-> Empty Wat Project). Then save and build; right click the new main.wasm and select "Generate Call Graph." That said, check out this encrypted and anonymous "pastebin" I built [2] with the crypto being written in Rust and bindings generated using wasm-bindgen [3]. It surprisingly hard to debug when optimized using wasm-opt [4].
