Comments in JSON

A common point of confusion, as the official JSON standard (RFC 8259) does not support comments.

Unlike JavaScript objects, standard JSON does not allow for comments (e.g., // or /* */). Including them will cause most parsers to fail. If comments are needed, for example in configuration files, formats like YAML or JSONC (JSON with Comments) are often used instead.
