Here follows a list of operators that applies to objects: In this list, o and o2 are used to represent object expressions, and s is a string expression:

o[s]

indexing, returns the identifier named s in the object o,

an identifier is a global variable or a function.

o[s]=c

This sets the global variable s int the object o to c,

if s is a function however, an error is produced.

o->foo

same as o["foo"]

o == o2

return 1 if o and o2 are the same object

o != o2

return 0 if o and o2 are the same object
