In React, you control branching logic with JavaScript. You can return a JSX expression conditionally with an if statement. You can conditionally save some JSX to a variable and then include it inside other JSX by using the curly braces. In JSX, {cond ? <A /> : <B />} means “if co...
Internet Explorer 8 no longer being supported likely means that some of the internal processes are more optimized. React 15 truly is faster in the rendering process, but only when built for production. Development mode is actually quite a bit slower, mostly because of the plethora of functionalit...

This means that by default, any JavaScript code that you run will block any other browser tasks from running, such as painting the screen. This is why it's especially important that JavaScript code be fast. However, in some cases, even the performance of the React reconciliation code isn't...

The end purposes of 3D modeling are broader: essentially, 3D modeling means creating a realistic digital twin of a real-world object, which can be used in countless applications across industries, from CGI and VR to healthcare and manufacturing. One common purpose is 3D printing, whether it be...
