Something that interested me this week

This week I had a fun time spewing memes and learning some new things. It was fairly busy with work, house projects, and emails otherwise, and I’m hoping this next week I can finish some reading and keyboard projects!

Meticulous is a tool for easily creating smoke tests to catch frontend regressions, without writing mocks. You can record workflows or sessions using our CLI, and replay those sessions against new frontend code, taking a visual snapshot at the end of a flow. You can then create tests by using our CLI tool to diff these replays.

Meticulous captures network traffic at record-time and mocks out network calls at replay-time, which removes the need to implement any mocks or for a backend environment to replay against. It also means it’s best suited to catching frontend regressions.

You can inject our JS snippet onto staging, local, dev and QA environments if you want to capture a larger pool of sessions and catch a broader range of edge cases.

You can read more at our docs at docs.meticulous.ai.

Interview question of the week

Last week, I had you figure out who owed what after a vacation. This was a sneakily tricky one, nice work Thierry, Aleksandr, Will, Les, Amine, Matteo, Giovanni, Leyan, Steven, Nicole, Philip, Ten, Divyansh, Conor, and Giancarlo!

This week’s question:
Given two integer arrays of size n, return a new array of size n such that n consists of only unique elements and the sum of all its elements is maximum.

Example:

let arr1 = [7, 4, 10, 0, 1]
let arr2 = [9, 7, 2, 3, 6]

$ maximizedArray(arr1, arr2)
$ [9, 7, 6, 4, 10]
