You changed the title from
_" JS ? in 100 seconds"_ to
_" ? in NaN seconds"_

Cool

I used to be very down on the ternary operator. I've come to see they have a place. Great mention of optional chaining I'm a big fan.

Hey Jeff,
We need a “Fireship answers in 100 seconds” 😄

Just so you know, your videos have changed my coding style over time. I keep learning new abilities, or nice features I didn't know about, resulting in me going back to my code and making changes with these cleaner solutions.

Your videos are having a direct impact on me. Thank you.

Phonology in ≈100 Characters
(1:48) The second ⟨c⟩ of _coalescing_ is silent as is so w/ many instances of ⟨sc⟩; consider, e.g., _science_, _ascend_, & _abscess_ .

It feels like I was waiting my whole life for JS to introduce optional chaining. Thanks for a great video!

[duuhhveeed]

Holy mackeral, ive been obj chaining recently and wanted to find a better solution and you just showed me something big. Fireship does it again

[mirandamoralez]

depth, sound, voice - so great always! THX A LOT!

[akashmelkeri]

it's been nearly 8 months since i started using js for work. and today i got to know 2nd and 3rd use of question mark. these 2 uses will save a lot of time for me buddy. thanks

[Nintron]

Watched this video and then 30 minutes later I needed some default value if one wasn't passed and remembered nullish coalescing from this video. Big thanks!

[reyanrahman]

U have no idea how much time this little question mark will save thank you so much keep making more shorts like this

[mirkosedda]

These videos are more valuable than they are short.. just brilliant job!

[quirky_hehe]

I'm a an experience developer and I actually learned something. Great videos as always!

[ThePayanazo]

Thanks for this man, i appreciate your teaching, for a person who is starting in this, this is literally gold.
