<p><!-- CL 153559 -->
<p>
The <code>Callback</code> type and <code>NewCallback</code> function have been renamed;
they are now called
<a href="/pkg/syscall/js/?GOOS=js&GOARCH=wasm#Func"><code>Func</code></a> and
<a href="/pkg/syscall/js/?GOOS=js&GOARCH=wasm#FuncOf"><code>FuncOf</code></a>, respectively.
This is a breaking change, but WebAssembly support is still experimental
and not yet subject to the
<a href="/doc/go1compat">Go 1 compatibility promise</a>. Any code using the
old name will need to be updated.
