Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / over 2 years ago

I'd recommend to play around with some basic coding challenges on leetcode.com or codewars.com. If the course prepared you well you won't find this useful, but playing around with them will make sure that you are comfortable with basics such as loops, if statements etc. Source: about 3 years ago
