I created a decorator called @Inject in typescript file, like this

export class A{
    @Inject()
    private b!: string

    @Inject()
    private c!: string
}

But vscode told me there was a mistake

export class A{
    @Inject()
    private b!: string

    @Inject() //error : Decorators must precede the name and all keywords of property declarations.
    private c!: string
}

But when I execute the TSC command, the terminal does not display any errors.

The strangest thing is that when I end with a semicolon, the error disappears.

export class A{
    @Inject()
    private b!: string ;

    @Inject()
    private c!: string ;
}
