In the Expression Syntax guide https://angular.dev/guide/templates/expression-syntax#what-operators-are-supported the following operators are listed under "Supported operators":

• typeof
• void
• in

However, these same operators are also listed under "Unsupported operators" just below, and when tested in templates, they do not work and result in template parsing errors.
