var keyword allows declaring multiple variables, separated by comma
,. Each variable has a valid identifier and optionally a value assignment following the assignment operator
=. Variables can also have an explicit type-hint.
var a; // declare local a var b:Int; // declare variable b of type Int // declare variable c, initialized to value 1 var c = 1; // declare an uninitialized variable d // and variable e initialized to value 2 var d,e = 2;
The scoping behavior of local variables is described in Blocks.
