Case Sensitivity Rules

Case sensitivity for keys, keywords, and type names.

Internet Object is case-sensitive throughout. Keys, keywords, and type names MUST be written with exact casing.

Keys

Member keys are distinct by case — Name and name are two different fields:

Name: string, name: string
---
{ Name: Alice, name: alice }

The literal keywords MUST be written exactly as defined. Their accepted forms are:

Meaning

N, null
