|
* SUMMARY: This test arose from Bugzilla bug 57043:
|
|
* "Negative integers as object properties: strange behavior!"
|
|
*
|
|
* We check that object properties may be indexed by signed
|
|
* numeric literals, as in assignments like obj[-1] = 'Hello'
|
|
*
|
|
* NOTE: it should not matter whether we provide the literal with
|
|
* quotes around it or not; e.g. these should be equivalent:
|
|
*
|
|
* obj[-1] = 'Hello'
|
|
* obj['-1'] = 'Hello'
|
