JavaScript Kicks - JSK Weekly - 13 September , 2023

React.js uses a number of unique concepts that can initially seem a bit confusing. One such concept is the use of keys, particularly when working with component arrays. Why and how do we use these keys? Check out Scott Robinson's "Understanding Unique Keys for Array Children in React.js" for all the details.

Other popular stories this week include "What’s New in 2022 Volume 4: Essential JS 2" on Syncfusion, "Page Transitions In Next.js 13 With App Router And The Built-In View Transitions API (No Third-Party Libraries)" and "A new method to validate URLs in JavaScript (2023 edition)".
