Why do I get Identifier Expected , and Statement expected here

Why do I get Identifier Expected , and Statement expected here :

model Person{
name?: string;
adress?: Address_1_0_0; // this is a seperate model defined 
age?: integer;

   
   ...AdditionalProperties<never>;
}

Nothing you pasted here has a syntax error. Can you include more context? A playground repro would be helpful too!

Sure , I got the same errors , when I paste it into the playground .

Ahh, the issue is that you have a property named "op", which is a keyword. You have to surround it in backticks like so.

Yees , it works now , thank you I've spent 3 hours blocked on that , is there any page that highlight the reserved keywords ? and also Syntax for naming properties , as my knowledge we can't start a property with a number and also with bracket ...

Sorry to hear! We don't have great docs on that, it's a good point that we should add it! If you can read formal grammar notation, you can find the spec here. In general we use the Unicode UAX31-R2 for identifiers, so in general word characters in any language, emoji, $ and _ are fine. Other symbols are generally not fine. Numbers can't start an identifier but can be present within an identifier.

Alright , thank you so much
