Subject [jira] [Commented] (COUCHDB-1397) Function expressions, evals in SpiderMonkey
Date Fri, 03 Feb 2012 15:23:54 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13199766#comment-13199766
] 

Paul Joseph Davis commented on COUCHDB-1397:
--------------------------------------------

Erm, I'd like to point out that the string "function(doc) {}" actually *is* invalid JavaScript.
Anonymous functions at global scope are specifically not ok. Although anonymous functions
in a statement context *are* ok. Its a subtle distinction but its quite important.

Also, just today I came across a scenario of compiling a regular expression outside the function
scope as a valid use of the "helper" pattern.

> New SpiderMonkey releases do not eval() a sole anonymous function expression. That is
not a valid JavaScript statement, and so it is not a valid JavaScript script.
> COUCHDB-1302 addressed this for 1.1 and the 1.1.x branch. This ticket is for 1.2. (Sorry
to spam COUCHDB-1302. I saw "Unassigned" and read "Unresolved.")
