Introducing: Array#Extras email course

Array#Extras

From the posts and guides in this blog, you can tell that I love working with collections. This is probably the aspect of programming that changed the most how I write code in the past decade.

And there are many ways to do it wrong and a few how to do it right.

For most of the day-to-day coding, for loops are a thing of the past, and the vast majority of them can be written in a way that is better suited for people than machines. But this way of handling collections requires a few building blocks. These are functions that are simple in isolation, but composing them forms the arbitrarily complex logic of modern programs.

This course introduces these building blocks and shows how to solve everyday tasks using them.

In 14 emails, you will learn:

• How to make an autocorrect using map
• How to speed up a crowded city map with many places using filter
• Use a simple some to check where a king can move on a chessboard
• Master reduce, the most versatile of all the Array functions

The course is 100% free and without any commitments. Unsubscribe at any time.

Check it out and give it a spin.
