Yes, that code will delete the title and mode properties from the this.args
object.
I'd go for consistent use of property names myself - you don't need to use
the quoted form:
var title = this.args.title;
var mode = this.args.mode;
delete this.args.title;
delete this.args.mode;
What didn't work? This code should do exactly what you expect. Your title
and mode variables now contain references to whatever was in this.args.title
and this.args.mode, but those two properties are now removed from this.args.
If console.log showed you something different, then there must be some other
code you didn't include in these snippets that is affecting it.
