![]() They include optional rendering of DOM elements, lazy loading, loading content on demand with infinite scrolling, rendering advertisement and animations, and creating carousels. Intersection Observer can be used for a wide variety of various applications outside of the scope of this article. ![]() However, updates can be found here.Īs for the browser compatibility, here is the current report: Specifications and browser compatibilityĪt the time of writing this article, the specifications are still a working draft. These situations include when the position of the selected element comes into the client’s viewport, when a selected element intersects a parent or root element, or when the observer is initially declared. How Intersection Observer worksīasically, the Intersection Observer API triggers a callback function in specific situations. Intersection Observer is JavaScript browser API that asynchronously monitors the position of DOM elements with respect to the client’s viewport or a root element. With Intersection Observer you can do all these. In this article, I will explain how Intersection Observer can be used to implement this autoplay and pause feature by creating a React custom Hook for use in a TikTok clone.Īs a developer, you might want to implement an autoplay feature in a video player application, lazy load an image, or detect when an advertisement is in viewport of a user’s browser. Have you ever wondered how social media applications like TikTok, Instagram, or Twitter detect a particular video post that is in the viewport, autoplay it, then stop it immediately after it goes out of view? Here's every Icon Series emote so far.Joel Adewole Follow Jamstack web developer | Technical writer | React | Python Build a custom TikTok autoplay React Hook with Intersection Observer These days, you'll find licensed music, popular dances, and more in the ever-expanding Fortnite Icon Series emotes library. It was only in 2021 when the TikTok dance emotes were all retroactively moved into the Icon Series, expanding the series enormously. ![]() That one is part of the Ariana Grande set and is still considered part of the Icon Series as a result even as, last we checked, Ariana Grande has not been seen riding a fantasy creature. Some other emotes are tied to artists even as they are wholly invented for Fortnite, like the Lil' Floaticorn emote, where players ride a llamacorn (llama unicorn). When a viral dance appears in Fortnite, it now tends to include attribution, citing its creator in the emote's details, which suggests a deal has been worked out with the original dancer or singer. Today, Epic may be more able to include these dances without the threat of legal action after setting a precedent with its past victory, but it seems the company has changed how it goes about its business anyway, just to keep things out of the courts. Icon Series emotes are among the most expensive, but also the most sought after in Fortnite. Most cases were eventually withdrawn when either the US Copyright Office denied copyrights or, in at least one case, Epic even won the lawsuit. This led to some legal trouble for Epic, which was sued by Alfonso Ribeiro and Backpack Kid respectively, among others, with dancers claiming ownership of the moves. There was a time when Epic skirted the line of including these dances the right way, like when popular dances such as The Carlton and The Floss were put in the game. With music ranging from Rick Astley's retro hit "Never Gonna Give You Up" to modern reggaeton hits like J Balvin's "In Da Ghetto," today the Fortnite Icon Series skins are joined by a growing list of dances made famous in music videos and TikTok. The Fortnite Icon Series isn't just home to some of the most popular character skins, it's also the rarity type for dozens of licensed songs and dances that players can use in-game. Today the game is, in many cases, already treated as the new social media for younger players who would rather socialize in Fortnite than post to Facebook and Twitter. Fortnite dances are just one part of Epic's quest to have the game become the all-encompassing hub of pop culture and social gathering space of the future.
