"We tried to put together all of your greatest moments, but the truth is, no one show can do them justice," Noah told Williams as she sat beside him on-set. "You are the coolest, most awesome person. This building is going to suffer a severe lack of J. Willy-ness without you."
The 32-year-old South African comedian then showed a compilation of some of her best moments, as well as sweet messages from fellow correspondents, before concluding the segment with more kind words.
"Jessica, we cannot say goodbye to you enough," he explained. "It is not goodbye, it is farewell. You're going to be close by, hopefully. Your show is going to be amazing, and you're always welcome [back]."
Williams is the first correspondent to leave The Daily Showsince Noah took over for Jon Stewart last fall. The 26-year-old comedian was the youngest correspondent to join the show when she arrived in 2012, and she quickly established herself as a distinct voice among them, often discussing topics of race and gender inequality.
At one point, she was even the favorite to replace Stewart after he quit the show following 16 years in the hosting chair in 2015, though that role eventually went to Noah.
It was announced in March that Williams is set to develop a scripted project for Comedy Central with Broad City writer Naomi Ekperigin. The network tweeted about her Daily Show departure on Wednesday.
