                      boolean isName)

The delete operator See ECMA 11.4.1 In ECMA 0.19, the description of the delete operator (11.4.1) assumes that the [[Delete]] method returns a value. However, the definition of the [[Delete]] operator (8.6.2.5) does not define a return value. Here we assume that the [[Delete]] method doesn't return a value.

name

public static java.lang.Object name(Context cx,

              java.lang.String id)

Returns the object in the scope chain that has a given property. The order of evaluation of an assignment expression involves evaluating the lhs to a reference, evaluating the rhs, and then modifying the reference with the rhs value. This method is used to 'bind' the given name to an object containing that property so that the side effects of evaluating the rhs do not affect which property is modified. Typically used in conjunction with setName. See ECMA 10.1.4

- it doesn't perform ToObject on the right hand side
- it returns true for DontEnum properties.

Parameters:

a - the left hand operand

b - the right hand operand

Returns:

true if property name or element number a is a property of b
