My approach contains some guesswork and might lack depth in a few areas. If you notice any mistakes or opportunities for improvement, the easiest way to reach out to me is either commenting under this Gist, or writing directly on Discord where I have the same nickname as here.

The problem

After profiling ESLint rules' performance in the Svelte repository, Ben McCann noticed that the n/prefer-node-protocol rule takes almost 50% of the total linting time: eslint-community/eslint-plugin-n#404. As with most issues I tackle, I wanted to start by reproducing the result, so I cloned the Svelte repository, installed the dependencies, and ran pnpm build.

Initially, I tried to check the performance in a more granular way with the --stats option (available in ESLint 9+, which is used in this particular project). This has proven unfeasible though as even when outputting JSON and redirecting stdo

If you want to learn Scala, I’d suggest:

• Install IntelliJ + Scala Plugin
• Don’t do the Coursera courses yet.
• Don’t do the “red book” Functional Programming in Scala yet.
• Do: http://underscore.io/books/
  • Essential Scala
  • Essential Play
  • Essential Slick
• Do Scala for the Impatient: https://www.amazon.com/Scala-Impatient-Cay-S-Horstmann/dp/0321774094

/**
 * This was something I explored today.
 * The approach is fundamentally flawed for a couple of reasons.
 * 
 * 1. play JSON serializes dates to strings,
 * but they are better represented as timestamps or ISODates in mongo.
 * 
 * 2. ObjectId's cannot be round-tripped, since they turn into JSON
 * strings on the way out.

Overview
--------

To run a query using anorm you need to do three things:

 1. Connect to the database (with or without a transaction)
 2. Create an instance of `anorm.SqlQuery` using the `SQL` string interpolator
 3. Call one of the methods on `SqlQuery` to actually run the query

README.txt - DIY Scala Enumeration
  Copyright (C) 2014-2016  Jim O'Flaherty

Overview:
Provide in Scala the closest equivalent to Java Enum
  - includes decorating each declared Enum member with extended information
  - guarantees pattern matching exhaustiveness checking
    - this is not available with scala.Enumeration
