GELLO is strongly typed. A hover hint over _Result_ shows the type is String. Lets see how we can find out the type in the workspcaeworkspace:
Assign the string to a local variable called a. Then check the type:
...
In the exe version of the editor the system would suggest we add the type at line 1. So let's do that, because GELLO is strongly typed; then delete line 2, and see if there are any errors. This time Debug GELLO says there is no final expression:
This is ok. GELLO is declarative. We haven't declared what we want the result to be. We would simply say a in line 2, but we could also say 1+1
Ok, to have fun with strings we could type a. and the autocomplete will show methods available for this datatype.
Let's play with the matches method, and yes the string called 'a' does match the parameter:
This works too:
a.matches('Gello|Hello') |
|---|
