### 简单的四则运算

```c++

const char *buffer = (env)->GetStringUTFChars(jsValue, 0);

JSValueRef exception = nullptr;

JSGlobalContextRef executor_context_ = ::JSGlobalContextCreate(nullptr);

JSStringRef script = ::JSStringCreateWithUTF8CString(buffer);

JSValueRef value = ::JSEvaluateScript(executor_context_, script, 0, 0, 0, &exception);

if (JSValueIsNumber(executor_context_, value)) {

    double result = JSValueToNumber(executor_context_, value, nullptr);

    LOGD("JSValueIsNumber: %f", result);

    return result;

}

::JSStringRelease(script);

```
