How to write if condition to exclude EmptyObject

[simPod]

I wonder how you guys do it.

I've been using Record<string, never> to represent {} but wanted to migrate to TypeFest's EmptyObject

I've been using Object.keys(foo).length === 0 to detect the empty object type but that does not work for EmptyObject. Is there a way to check for it without typecasting or creating custom typeguard?

var foo: EmptyObject | Record<string, number>;

if(Object.keys(foo).length === 0) {
   // EmptyObject here
} else {
  // Record<string, number> here
}

You need to use a check function with a better type-guard, like: https://github.com/sindresorhus/is#emptyobjectvalue
