== Why is this an issue?
|
|
|
|
The semantics of the ``++delete++`` operator are a bit tricky, and it can only be reliably used to remove properties from objects. Pass anything else to it, and you may or may not get the desired result.

=== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
var x = 1;
|
|
delete x; // Noncompliant
|
|
|
|
function foo(){
|
|
..
|
|
}
|
|
|
|
delete foo; // Noncompliant
|

|
=== Compliant solution
|
|
|
|
[source,javascript]
|
|
----
|
|
var obj = {
|
|
x:1,
|
|
foo: function(){
|
|
...
|
|
}
|
|
};
|
|
delete obj.x;
|
|
delete obj.foo;
