Protips

This site lists the protips that we shared with each other in the Slack-channel during the courses.

I wrote many of these blog posts using JavaScript since that was the language that we used in the initial courses. The same concepts apply to other languages for the vast majority of those blog posts. When it doesn’t we have broken them out to separate headings per language.

The code for the blog posts (where they have code) can be found here
