Identifiers

Identifiers name variables and are used in property access expressions. They are case-sensitive.

Rules

• Must begin with a letter (a–z, A–Z) or underscore (_)
• May contain letters, digits (0–9), and underscores
• Cannot be a reserved keyword (except when used as object property names)

Naming Conventions

Usage	Convention	Example
Local variables	lowerCamelCase	orderTotal, itemCount
Private/internal variables	underscore prefix	_payloadData, _metadata
Iterator variables	match the collection name	foreach item in Data.items

Function names are host-provided and always PascalCase (e.g., ToUpper, WhereByField). The Data identifier is reserved and always PascalCase.
