unProtect method
void
unProtect()
Protects a JavaScript value from garbage collection. Use this method when you want to store a JSValue in a global or on the heap, where the garbage collector will not be able to discover your reference to it.
A value may be protected multiple times and must be unprotected an equal number of times before becoming eligible for garbage collection.
Implementation
void unProtect() {
JSValueRef.jSValueUnprotect(context.pointer, pointer);
}
