const nativeArithmetic = require('./build/Release/arithmetic.node');
exports.increment = function(n) {
    if (typeof n !== 'number') {
        throw new Error("Expected one numeric argument");
    }
    return nativeArithmetic.increment(n);
};
```

Our wrapper module checks types before calling into the native module.
