Public rest parameters in constructor

Question

i watched a tutorial of typescript, that uses Version 1.0.0. There was a sample of a class, using a public rest parameter in the constructor:

class XYZ {
   constructor(public firstname: string, public lastname: string, ...public emails: Array<string>) {
    }
}

How to do this in Version 1.5.0? If i define the class like this, i got several errors:

type.ts(14,75): error TS1005: '=' expected.
type.ts(14,81): error TS1005: ',' expected.
type.ts(14,88): error TS1005: '=' expected.
type.ts(14,96): error TS1109: Expression expected.

Thanks Mario

Answer 1

There is an oversight in the spec, but the rest parameter can't be public or private. Here is how to fix the code:

class XYZ {
    public emails: string[];
    constructor(public firstName: string, public lastName: string, ...emails: string[]) {
        this.emails = emails;
    }
}
