\emph{Boolean} is type of the value that is either \codebf{TRUE} or \codebf{FALSE}. Number \codebf{0} and \codebf{FALSE} make the condition \emph{false}. When used in numeric context, \codebf{FALSE} will be interpreted as 0 and \codebf{TRUE} as 1.
\emph{String} represents immutable\footnote{Cannot be altered directly} sequences of bytes. However, you can't weave them to make something like \emph{string array}\footnote{Future feature\ldots\ maybe\ldots? Probably not\ldots}.
\emph{String} represents immutable\footnote{Cannot be altered directly} sequences of bytes.
\emph{Array} represents a collection of numbers in one or more dimensions.
