Optimizing user experience remains paramount in contemporary web development, especially considering ever-shrinking attention spans and escalating performance expectations.
One proven technique for accomplishing this feat entails lazily loading JavaScript modules, thereby deferring noncritical assets until genuinely needed.
Consequently, initial payload sizes diminish significantly, leading to expedited render times and enhanced overall satisfaction.
Dynamic Imports to the Rescue
Fortunately, recent advancements in ECMAScript standards paved the way for dynamic imports, empowering developers to request discrete chunks dynamically. Consider the subsequent example illustrating its employment:
Suppose we possess a sizable library comprising assorted widgets, yet users predominantly interact with merely a handful. Clearly, bundling everything collectively proves wasteful and detracts from perceived responsiveness.
Therefore, let’s segregate these popular items into individual modules, subsequently incorporating them judiciously per demand.
