Convert the value to a boolean. <p>See ECMA 9.2.

The typeof operator

Internal method that reports an error for missing calls to enter().

Not all "NativeSymbol" instances are actually symbols. So account for that here rather than just by using an "instanceof" check.

Builds and returns the {@link JSCode} object.

Get a context associated with the current thread, creating one if need be. The Context stores the execution state of the JavaScript engine, so it is r
