Is this regular expression?
regex, unity-game-engine, unityscript
Solution
As many have already mentioned, `" "[0]` is the first character of the `" "` string (which is a `System.String`, or an array of `System.Char`s. The problem with UnityScript is that `' '` is interpreted as a String too, so the only way to provide a Char is by slicing.
Problem
This is how to split string in Unityscript from Unity Wiki. However, I don't recognize `" "[0]`. Is this regular expression? If so, any reference to it? I'm familiar with regular expressions generally and used them a lot, but this syntax is little confusing. ``` var qualifiedName = "System.Integer myInt"; var name = qualifiedName.Split(" "[0]); ``` Wiki Reference
