[JASS] What is that?

[Geries]

I don't know what is that but when I was looking for useable characters I have found this: & My jass helper highlights this. So I am interested in now

If you're using ZINC syntax then you use a double ampersand "&&" instead of the "and" keyword in conditional statements. If your just using basic vjass or jass syntax then I don't think there is any use for it (but I could be wrong).

I see. Well I didn't know that. Almost impossible to look after this and it returns no good to search & in hive. Btw ZINC is quite far from me. Why they can't write "and". How lazy...

Because &&/|| are standard for and/or. If you look up truth tables, you'll see why the double chars are used. &/| are used for bitwise comparisons.
