+### JavaScript Source Maps
+
+JavaScript source maps, which are used by browser developer tools to provide source-level debugging experiences, are [standardized](https://sourcemaps.info). These can be indexed by the 
+[SHA-256 hash of the script file they map](https://chromedevtools.github.io/devtools-protocol/tot/Debugger/#event-scriptParsed)
+(see the `hash` property of the linked event).
+
+Example:
+
+**File name:** `main.js`
+
+**SHA-256 of file:** `e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855`

+### WASM (WebAssembly) Modules
+
+WebAssembly symbols, which can be used by browser developer tools to provide source-level debugging experiences, are based on the DWARF format. These are indexed by their DWARF Build ID 
+(built with `-Wl,--build-id` arguments) and the name of the module being debugged via the 
+[buildId property](https://chromedevtools.github.io/devtools-protocol/tot/Debugger/#event-scriptParsed), and the symbol file itself is suffixed with `.s` to disambiguate from the WASM file.
