But for now, we must solve another pressing issue - our code is not very modular. Everything is defined inside a single <script> tag. Not only is this hard to read, but it is also not maintainable. We can't define every component in one file!
Furthermore, we are including libraries using <script> tags. Because some libraries depend on others (for example, react-dom depends on react), we must manually ensure our scripts are loaded in the right order.
We have already looked at CommonJS and ES6 modules when we discussed server-side modules. However, we must consider other factors when using modules on client-side code, such as:
- The size of each module. Dependencies are downloaded before the application is run. On the server, the application is only initialized once, after which it will keep running for a long...
