JSFunction* myFunction = JSFunction::Create(context, "myFunc", 0); JSString* result = myFunction->Call(context, global, argc, argv);
JSFunction* addFunc = JSFunction::Create(context, "add", 2); JSValue* args[2] = { JSNumber::New(context, 1), JSNumber::New(context, 2) }; JSString* result = addFunc->Call(context, global, 2, args);This code creates a JavaScript function called "add" that takes two arguments. It then calls the function with arguments 1 and 2, and returns the result as a string. JSFunction is part of the SpiderMonkey JavaScript engine, which is used in various packages and libraries, including Firefox, Node.js, and the Mozilla Rhino JavaScript interpreter.
