Something that interested me this week

This week felt like it went super fast with the American holiday on Monday! I spent some good times with family and friends, experimented with React Native (maybe I'll have something to show later? Maybe?), and spoke at TheJam.dev (recordings available soon)! It's hard to believe how fast February went, but I'm glad to have some more sunny days coming soon with all the cold and snow we've had in Chicago.

Sponsor

No sponsor! Be free from capitalism!

...But also it'd be cool if your company would be down to sponsor, because though this newsletter is free to read, it's not free to make!

There's some info here if you wanna pass it along to decision-makers in your org.

Or, if you'd like to help support my work individually, you can use Patreon or GitHub Sponsors (both of which get you access to a very fun Discord group)!

Interview question of the week

Last week, I had you determine if a spaceship shield was safe. Pew pew good for you Amine, Ricardo, Jeremias, Miguel, Tim, Austin, Vanessa, Muhammad, Szymon, Saleh, Kyle, Ashish, David, Neha, Nwosa, Winnie, Ten, Max, and Ross!

This week's question:
Given a list of frequencies (in Hz), write a function to determine the closest musical note for each frequency based on the A440 pitch standard. Extra credit: indicate if the note is flat or sharp!

Example:

> getNoteNames([440, 490, 524, 293.66])
> ["This is a A", "This is a B, but it's flat", "This is a C, but it's sharp", "This is a D"]

(you can submit your answers by replying to this email with a link to your solution, or share on Bluesky, Twitter, LinkedIn, or Mastodon)
