Something that interested me this week

I wrote about how I built my cry-tracking app, Ductts this week! I feel like besides that and swiffering my floors, I haven't gotten a lot done lately. My new baby is turning four months old (!) today, and between him and my toddler, we're just constantly chasing, feeding, changing, reading to, and playing with them. It's fun, it's good, and I'm grateful for maternity leave, but... I'm so exhausted all the time. I know it'll get easier eventually, so I'm staying as positive as possible and trying to savor the small moments (...and crying about them and logging into Ductts very often). Parenting is the most challenging joy, ever.


Sponsor

No sponsor this week! Please consider checking out one of the apps I've made recently:

  • Ductts
  • PocketCal
  • W-9 Crafter

Or, if you feel so inclined to help support my work financially in other ways, 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 make a laundry generator function. Squeaky clean good job Paul, Ten, Ender, Ida, Collin, Miguel, Elke, Jonathan, Kriszti, Dani, Vasanth, Andrew, Pedro, Victor, Christian, Stephen, Laasya, Amine, and Jeremias!

This week's question:
Given an array of order objects for a restaurant, each with a table number and a list of ordered items, write a function that returns an object mapping each table number to a summary of how many times each item was ordered at that table. Extra credit: Could you go so far as to make this a restaurant management game?

Example:

const orders = [
  { table: 1, items: ["burger", "fries"] },
  { table: 2, items: ["burger", "burger", "fries"] },
  { table: 1, items: ["salad"] },
  { table: 2, items: ["fries"] }
];

> orderSummary(orders)
{
  1: { burger: 1, fries: 1, salad: 1 },
  2: { burger: 2, fries: 2 }
}
// or, string output format:
"Table 1 ordered 1 burger, 1 fries, and 1 salad. Table 2 ordered 2 burgers and 2 fries."
