|
summary: |
|
|
|
|
|
<p>Replace the current context's global object with the object on top of the
|
|
|
|
|
value stack. If the value is not an object, an error is thrown.</p>
|
|
|
|
|
|
|
|
|
|
<p>Note that this operation <b>does not</b> affect the global object of other
|
|
|
|
|
contexts, even those that have up to this point shared the same global
|
|
|
|
|
environment. To inherit the change to other contexts, replace the global
|
|
|
|
|
object first before calling <code>duk_push_thread()</code>.</p>

This API call is experimental at present, and some of the semantics may
