"Iterating Over Any JavaScript Object" example does not compile

[sandromario]

The following code from the example "Iterating Over Any JavaScript Object" (https://rustwasm.github.io/wasm-bindgen/reference/iterating-over-js-values.html#iterating-over-uanyu-javascript-object-that-implements-the-iterator-protocol) does not compile:

let iterator = match js_sys::try_iter(some_iterable)?.ok_or_else(|| {
        "need to pass iterable JS values!".into()
    })?;

This is the output I get:

   |
86 |     let iterator = match js_sys::try_iter(some_iterable)?.ok_or_else(|| {
   |                    -----
   |                    |
   |                    while parsing this match expression
   |                    help: try removing this `match`
87 |         "need to pass iterable JS values!".into()
88 |     })?;
   |        ^ expected one of `.`, `?`, `{`, or an operator here

Oops, thanks for the report!

There's one more:

error[E0599]: no method named `is_f64` found for type `wasm_bindgen::JsValue` in the current scope

[sandromario]

And also, if I comment the is_f64 line out, I get:

error[E0282]: type annotations needed

Oops, should be fixed now too!
