Syntax

Field Definition

• Fields must exist in the object that was passed.
• A point (.) in the field name signals index access, so a field named friends.0.address.street would also translate to a call to data.friends[0].address.street.
• Fields must start with an alphabetical character and can contain only alphanumeric characters, ., and _, unless surrounded by accent quotation marks, e.g. `$up30dy`.

Value Definition

• Values can either be numeric (e.g. 18 or 3.14) or must be surrounded by single or double quotation marks (e.g. 'James Bond').
• Arrays can be defined using parentheses and can only be combined with the operators in and not in. Array items are separated by using a space or a comma. E.g. city in ('Berlin', 'Paris', 'Athens') and city in ('Berlin' 'Paris' 'Athens') are equivalent.

The escaping symbol \ can be used to escape quotation marks inside a field or value definition.
