Arrays are created by enclosing comma-delimited expressions in square brackets like so:

["a", "b", "c"]

Arrays use zero-base indexing and can be referenced in the usual manner:

a = [1,4,3,6,5];

...

b = a[1] // b =

...

Note that array references only work for arrays of one any dimension. For example, c[1][2] is not allowed (presuming c is an array of arrays). Multidimensional arrays can be dereferenced using the pick operator (described momentarily).

Operations on Arrays

There are a number of operators that work on arrays. In addition there is an array membership infix operator.
