You can use vm.typeof(handle)
, which returns a string describing the type of the handle.
If the function wasn't defined, vm.typeof
will return "undefined"
here. If it's a function, it will return "function"
.
Example:
vm.evalCode('function hello() { return 42; }');
const maybeFnHandle = vm.getProp(vm.global, 'hello');
if (vm.typeof(maybeFnHandle) === 'function') {
vm.callFunction(handle, vm.undefined);
}
