A quality class that you can learn easily and quickly! Are you too bored to study regular expressions on your own? I highly recommend this course to those people. The lectures are not long and are organized compactly, so you can learn quickly and easily. While studying the basics of the JavaScript language, regular expressions came up and I was worried, and then the Life Coding Regular Expressions course happened to open and I took it. I personally took notes separately because there were many concepts that I felt I had to memorize. I think it would be good to make notes while watching the lecture.
