|

<p>This function will throw a JS exception with the JS value provided. This
|
||
function will not return and the wasm stack will be popped until the point
|
||
of entry of wasm itself.</p>
|
||
<p>Note that it is very easy to leak memory with this function because this
|
||
function, unlike <code>panic!</code> on other platforms, <strong>will not run destructors</strong>.
|
||
It's recommended to return a <code>Result</code> where possible to avoid the worry of
|
||
leaks.</p>
