"I didn't have any idea HOW IMPORTANT they were..."

This training is for developers who want to understand the WHAT, WHY, and HOW, instead of copy-pasting the code from StackOverflow.

The skill of understanding "the reasoning behind" is the 💪 superpower of top developers in the world that are in the highest demand!
