GET /compute (loading a big JSON file multiple times using a synchronous method). This latest version brings several features and improvements that must excite developers, incorporating the capacity of storing data through an online request, and in-built diagnostic reporting. We dont need to care about multiple different browsers and support for them, so whats the point of installing a tool that was made precisely with that in mind (Babel/Webpack etc.)? v12 is outon schedule! The library claims to be faster by 116%. Learn more about Teams As more and more assets are being served by our servers, we increasingly struggle with loading times. Instead of returning a misleadingERR_ASSERTIONerror, the methods indicate if there are arguments missing with theERR_MISSING_ARGSerror code. Use of them does not imply any affiliation with or endorsement by them. Some of those changes had a deprecation message in v3. Like other features, it requires getting sufficient usage that the APIs are in the proper shape and can be maintained. Two of them pertain to the availability.
