Something that interested me this week

Like I mentioned before, this week's newsletter marks its 3rd anniversary! A lot has happened in the past year with this project, including switching to new providers to handle the load of all the subscribers (that's you), a new domain for it (including a new base domain I set up this week to reduce the false spam in some people's inboxes), and literally thousands of new readers.

That being said, there are wonderful people here who would like to give away some things to you to celebrate!

Bryan Robinson is giving away 10 free licenses to his Practical CSS Grid course!

TheKey.Company is a premier vendor who designs products inhouse and with collaborators. This includes keyboards, keycaps, and related mech-cessories. They are raffling 1 set of Keyreative Blank Keycaps (any color in stock, winner's choice!) and any T-shirt from their In Stock selection! You can subscribe to their newsletter here.

Baking sourdough bread while stuck at home? Win a DIY bread timer party pack from @ChloeCondon! You can check out the full project here.

Gant Laborde over at Infinite Red Academy is giving away 5 free licenses to their Beginning Machine Learning with TensorFlow.js course!

Ryan is offering free resume reviews and mock interviews to readers who are on the job hunt! This isn't a raffle item, to sign up go ahead and fill out his form here.

Name.com is offering 4 coupons for a free domain, free advanced security, and a year of their Namebuilder hosting!

And I'll be mailing out some fun cassidoo stickers!

How do you enter the raffle for these things? You fill out this form by this next Friday at noon Pacific Time! I'll be using a random number generator to pick the winners and will email you separately to get things over to you. Thanks everyone for offering up such wonderful prizes! If you have something you want to offer as well, let me know, we can just have more winners!

It's been a blast running this newsletter and I don't plan on stopping anytime soon. Luckily, thanks to my Patreon and generous sponsors, costs don't have to come out of pocket for me nearly as much, and I can continue spending time putting this together for you every week.

Thank you again for sticking with me all this time, here's to another 3 years!

Sponsor

This week’s sponsor is Pluralsight! With more people working remotely than ever, Pluralsight is generously making its platform free to individuals for the month of April!

Sign up now (no credit card required) and through May 1st, 2020, get free access to over 7000 expert-led courses. This is huge, my mind was blown when I saw that they were offering this. Pluralsight has really excellent content, and I’m so grateful to them for their sponsorship and courses during these tough times!

Thanks Pluralsight!

Interview question of the week

Last week, I had you implement a "broken calculator." We had a ton of responses! Excellent work Sophie, Jonny, Ten, Jesse, Sameer, Axel, Joseph, Dimitris, Denis, Alejandro, Jasper, Jennifer, Thanos, Riana, Nikos, Herbert, Collin, and Rishabh!

This week's question:
Given two strings n and m, return true if they are equal when both are typed into empty text editors. The twist: # means a backspace character.

Example:

> compareWithBackspace("a##c", "#a#c")
> true      // both strings become "c"

> compareWithBackspace("xy##", "z#w#")
> true      // both strings become ""

I interviewed a TON this past week working to get a new role since my previous company had to lay off all staff a couple weeks ago. I wanted to get ahead of any potential hiring freezes, so I tried to not waste any time in finding a new role. And, I'm very excited to say that I accepted a role at Netlify as a Principal Developer Experience Engineer!

I'm so pumped to start this new job. The team is ~40% women and non-binary folks (which is RARE) and my future manager Sarah will be the first female manager I've ever had! I've never been in a work environment with numbers like these, so I'm really thrilled to be a part of that. The team was all super kind and funny when I spoke with them, too. Also, of course, the job seems like it'll be a blast. I'll be focusing on React and Next.js, and until I start in April, I'll be just messing with code waiting to start!

Interview question of the week

Last week, I had you build a string compressor! Great job Ten, Sophie, Dimitris, Sameer, Duncan, Quentin, Maty, Stuart, Giannis, and re:fi.64!

This week's question:
You're given a broken calculator that has a number showing on its display. You can only perform two operations:

Double the number on the display

Subtract 1 from the number on the display

Write a function that takes in the number X (the initial number on the display) and Y (the result that you want) and returns the minimum number of operations needed to display Y.

Example:

> brokenCalc(3, 10)
> 3                // 3 -> 6 -> 5 -> 10

It was a bit of a whirlwind for me over the past week; unfortunately, my company had to lay off all full time employees, so I'm currently on the job hunt. It's a bummer, but I'm trying to look at the positives, and am excited about future opportunities. Anyway, onwards!

As you can imagine, after my boss Ryan tweeted about what happened, a flood of DMs came towards me and my coworkers, and we're all feeling so blessed. If you are looking for a gig, or if you're hiring, check out this thread on Twitter for both people looking for jobs and hiring!

Interview question of the week

Last week, I had you build something with this free COVID-19 API. Amazing work Ten, Dimitris, Pariatol, Sarah, David, Leyan, and Alessandro!

This week's question:
Given a sorted array of characters, compress it in-place.

Example:

compress(["a","a","b","b","b","c","c"])
> ["a","2","b","3","c","2"]
// "aa" is replaced by "a2", "bbb" is replaced by "b3", "cc" is replaced by "c2".

I'm not sure what to expect in the coming months, but I hope y'all stay clean and healthy!

Write an event emitter that has three methods: on, emit, and removeListener.
The `on` function takes in an event name and a callback function, the `emit` function takes in an event name and data (which will be passed to the associated callback), and `removeListener` takes in an event name and a callback to remove from that event.

Aloha!

I hope you all had a wonderful week. I am currently in Hawaii after a fun time emceeing JSConf Hawai'i this past week! I'll be sad to leave the islands, but I'm excited to get home, too. Anyway, away we go!

Something that interested me this week

Like I mentioned before, I'm in Hawaii right now with my husband Joe! We're doing a little mini vacation after an eventful week at JSConf Hawai'i. The conference was SO fun. The coolest part about it was that it was a 2 day event, but there was a "Gap Day" in between for fun activities like a luau, board games, snorkeling, and exploring the island. The actual conference days were great too! Being the emcee, I threw a lot of jokes at the audience throughout each day, and enjoyed the variety of talks from a diverse set of speakers. I highly recommend checking out the tweets from the event, and keep an eye out on their official account for the videos of the talks!

Don't forget, my Kickstarter project is still live! It's officially fully funded now (woo hoo!) and I am so grateful for any and all support! If you'd like to join in, you still have time (about 20 days until it finishes up).

Interview question of the week

Last week I had you remove characters from a string to make the string an "even word." Great job Sophie, Stefan, Tamás, Ten, Nwosa, Jakob, Daniel, Dimitris, Samy, Mauro, re:fi.64, Kyle, Denis, Cédric, Chris, Leslie, Ana, Mayra, Jesús, Ritwik, Stuart, Carlo, and Vivek!

This week's question:
Given an array of points that represent the 3 vertices of a triangle, and a point K, return true if K is inside the triangle.

Example:

let triangle = [ [0,0], [0,3], [4,0] ]

isInTriangle(triangle, [2,1])
> true

isInTriangle(triangle, [3,2])
> false

Man, last letter of 2019, how wild is that?? It's been a busy year (and decade, for that matter) for me.

I worked at CodePen for a little more than the first half of this year, and had a great time doing it. I helped release features like the mobile editor, sections of the site on the new React stack, and the new Babel processor! As much as I loved it though, I was missing interacting with the dev community. I joined React Training to teach workshops, build curriculum, and work on open source. I was sad to leave CodePen, but am SO happy in my new job. The team is great, the work is fun, and I am really excited to see where this company goes!

Outside of my day job, I spoke at a few conferences like DinosaurJS and React Loop, started writing Stack Overflow's newsletter, I made my own LLC for my side projects, launched Astrolokeys and DSS Tecla, started making silly videos on Twitter, started and stopped grad school, visited Hong Kong, South Korea, Spain, and the UK, started my Patreon, laser cut and 3D printed stuff with my sister, rewrote my personal website, and drank tons of bubble tea with friends.

This decade, I graduated both high school and college, had several jobs, lived in 7+ cities, got married, bought a house, traveled a bunch, and... drank tons of bubble tea with friends. I can't wait to see what the next one brings!

I played the board game Wingspan for the first time this week, and it was a WONDERFUL experience! I really, really enjoyed it. It wasn't too long, has beautiful art, had some complex ideas (which makes me excited to play it again), and the parts were all pretty high quality, too. I love a good board game, so I'm really excited to add this one to my repertoire!

I ended up looking up the designer of the game, Elizabeth Hargrave. I was pleasantly surprised to see that the designer and all of the artists behind Wingspan were women (which is rare) and I had to learn more! She seems to be a fascinating person, and my favorite thing about her website by far was her database of Women and Nonbinary Board Game Designers. Check it out!

Interview question of the week

Last week I had you write a JSON parser! Quite a few people sent in answers like Ali that used JSON.parse(), which yes, is totally valid. But, Tan went above and beyond and not only wrote a parser from the ground up, but also wrote a super helpful blog post about it (and I saw it featured in JavaScript Weekly this week, amazing)! Good work Tan (and Ali + others)!

This week's question:
Given a positive number N, generate binary numbers between 1 to N using a queue-type structure in linear time.

Example:

> binaryQueue(10)
