030： When the following code: if map == nil {
log.Fatal("map is empty")

When running, the log statement is not executed, but the fmt.Println(map)representation map is empty: map[]
Jacob: You can use len: if len(map) == 0 {

Zac Delventhal Using traditional objects in JavaScript, it's easy to check if it's null using :Object.keys const emptyObj = {};
console.log(Object.keys(emptyObj).length === 0); // true, i.e. "empty"
const populatedObj = { foo: 'bar' };
console.log(Object.key

montekristo_07 I am trying to check if a map is empty or not in c++. However, while the map is not, there is a segmentation fault NULL. The code is simple, here: void func(std::map<std::string, std::vector<Foo*> >* myMap){
if(myMap == NULL)
std::cout
Andrew Swan I've read the documentation on Google Soy/Closure templates , but can't find any way to check if a map is empty; I can only look at the map's value for a given key. Is there a way to find out the size of the map? My current workaround is to replace

registration code The map is defined as follows: Map<String,dynamic> allAvailableTime;
When the user initializes the page, the map should be empty: I want to perform a null check before getting the data from the map, but none of these work... Check 1: allAvai
