This example illustrates side effect handling with dynamic imports: 1) Some libraries (like chart.js in this example) register global objects as a side effect when imported, 2) Dynamic imports execute these side effects when the module is loaded, just like static imports, 3) The code waits for the side effects to complete before using the global object, 4) This pattern is useful for on-demand loading of third-party libraries that don't use modern export patterns, 5) It's a practical way to deal with libraries that weren't designed with tree shaking or ES modules in mind, 6) The approach delays loading heavy libraries until they're actually needed, 7) It's a common pattern when integrating older libraries into modern applications, 8) While not ideal from a pure architecture perspective, it's often necessary for practical reasons.
