In the last two articles, we solved two exercises, one based on comparisons, and the other one on closures. Our third and final exercise from the book will be on the topic of prototypes. We picked these exercises up from Kyle Simpson’s You Don’t Know… Read More »JavaScript – Practicing Prototypes
In the last part, we did some work on comparisons, solving an interesting exercise. Now – we’ll learn more about Closure by solving another fun exercise. Just to remind you – we picked these exercises up from Kyle Simpson’s You Don’t Know JS book series,… Read More »JavaScript – Practicing Closure
I found some interesting exercises in the new, second edition of Kyle Simpson’s You Don’t Know JS series. At the end of the first book, he provided the reader with some practical examples of the topics learned. This time we will be solving a neat… Read More »JavaScript – Practicing Comparisons
What are the differences between function declarations and function expressions? We’ll find out in this article. We know how to write functions in JS, right? We use the function keyword, whose main role is to create a function. But did you know that there are… Read More »JavaScript – Function Declarations vs. Function Expressions
