Are functions passed by reference or value
All the documentation i can find (ex: msdn jscript documents ) says functions, like other objects, are assigned to variables by reference.
Code:
foo = new Function ('var u="*************";');
var bar = foo; // creates a ref or a copy ?
foo = new Function ('var u="_____________";'); //clobber foo
alert( [ foo.toString(), bar.toString() ].join("\n\n"))
this alerts:
Code:
function anonymous() { var u = "_____________"; }
function anonymous() { var u = "*************"; }
if foo was assigned to bar by reference, why does bar not reflect the current value of foo?
is there a rule or convention that controls when functions are passed by value -vs- when they are passed by reference ?
