What is the differences in nuances between とうとう and やっと?

is it true that やっと has a more "happy" feeling attached to it?




やっと means that something realizes after spending/waiting a long time for it or
making a lot of effort for it. Therefore it is understandable that やっと has a
happy feeling attached to it. If I understand English correctly, “at last” has
a similar meaning.

とうとう means that something happens as a final outcome, and what happens can be
either a good thing or a bad thing.

For example, suppose that some company has been financially in a trouble for a
while. Today you heard that the company went bankrupt.

> あの会社、とうとう倒産したそうだよ。 (あのかいしゃ、とうとうとうさんしたそうだよ。) I heard the company finally went
> bankrupt.

is a usual sentence. If you say

> あの会社、やっと倒産したそうだよ。 (あのかいしゃ、やっととうさんしたそうだよ。) I heard the company went bankrupt
> at last.

that means that you were waiting for the bankruptcy of the company.
