Applications running in web browsers are becoming increasingly sophisticated with each passing day. There would be nothing wrong with this if it weren't for the fact that, proportionally to the complexity, the amount of data required to be delivered over the network also increases. What can we do about this? In this lecture, you will learn how the dynamic imports work. We will cover the topic from the basics to practical applications. You will discover that the classic division by route is no longer sufficient, and you will learn how to do it better. With this knowledge, you will make your applications load much faster and will also reduce the burden on the processor, which will undoubtedly have an impact on the values of your metrics.
