Hello,
A question I get from time to time in training: What is the difference between .count and .length properties? Well, I admit having a lot to explain in a non-extendable time lapse often my answer is for lack of time : “They can give in some cases the same result but they are different”.
Here I take the time to elaborate a bit more!
The result is the same
We can see that .count always displays the number of objects
For the .length property, the result depends on the type of the object:
- Number of characters for a String type object
- Number of objects for an array
- Size for an object of type ‘File’
- …
If you want length to also display the number of objects, make sure you return a collection
