'of' vs 'from' operator

Question

Is the only difference between Observable.of and Observable.from the arguments format? Like the Function.prototype.call and Func

1. from returns notification in chunks i.e. one by one. for eg: from("abcde") will return a => b => c => d => e
2. of returns complete notification. for eg: of("abcde") will return abcde.
