I read the ES6 book so smoothly and it helped me understand parts that I didn't understand even after looking them up more than 10 times elsewhere, so I became a real fan. As a beginner working with JavaScript, I came across Youngbo's book and searched for it and even took the lecture! Thank you so much for making JavaScript feel more familiar. It's my job to utilize it, but I feel like I've grown a step because I'm reading code with meaning rather than just reading code.
