|
* SUMMARY: A class A should not see a global variable if the latter
|
|
* is defined too late. But what exactly is "too late"?
|
|
*
|
|
* In this test, the global variable in question is "objB". To define
|
|
* it "too late", it would not be enough to have 'var objB = etc.'
|
|
* as the last line of the script. All top-level var statements
|
|
* are "hoisted" and processed FIRST (before any assignments).
|
|
*
|
|
* So we define objB on the last line with a 'var'. That should make
|
|
* the test pass. The fact that objB is an object variable is immaterial.
|
|
*
|
|
* This test is just like test 'class-018-n.js', except on this point.
|
|
* Class-018-n.js omitted the 'var', to generate an exception -
