#Notes

Use .getClass() after any variable to print the class.

Define lists and maps e.g. list = [], map = [:]

You can either use dot notation or square brackets notation to reference the keys to get the values e.g. map.Key1 or map["Key1"]

##Closures

These are blocks of code which can be passed around in variables and passed to certain methods.

By default they take one variable called it.

square = { it * it }
println square(9)

[0,1,2,3].collect(square)

will perform the function square on each member of the list and return a new array
