Overview

The JadeSerializer is used in order to convert a JadeObject to a string. Once it has been serialized into a string it can be saved to a file or sent as text.

Formatting (with pretty printing):

<variableOne>: ‘<valueOne>’;

<variableTwo>: ‘<valueTwo>’;

Formatting (without pretty printing):

<variableOne>: ‘<valueOne>’; <variableTwo>: ‘<valueTwo>’;

: -> Splits the variable and its value

; -> Denotes an end of line

‘ -> Surround the value of the variable

“ -> Can also surround the value of the variable

When parsing Jade ignores ALL whitespace, even in variables.
