JavaScript to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in JavaScript and Rust so that programmers most comfortable with JavaScript can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

Introduction

At DICOM Grid, we recently made the decision to use Haskell for some of our newer projects, mostly small, independent web services. This isn't the first time I've had the opportunity to use Haskell at work - I had previously used Haskell to write tools to automate some processes like generation of documentation for TypeScript code - but this is the first time we will be deploying Haskell code into production.

Over the past few months, I have been working on two Haskell services:

A reimplementation of an existing socket.io service, previously written for NodeJS using TypeScript.
A new service, which would interact with third-party components using standard data formats from the medical industry.

I will write here mostly about the first project, since it is a self-contained project which provides a good example of the power of Haskell. Moreover, the proces

LOAD CSV into Neo4j quickly and successfully

Since version 2.1 Neo4j provides out-of-the box support for CSV ingestion. The LOAD CSV command that was added to the Cypher Query language is a versatile and powerful ETL tool. It allows you to ingest CSV data from any URL into a friendly parameter stream for your simple or complex graph update operation, that … conversion.
