HTML5 7 Advantages for Developers Cross-platform: In the multi-screen era, the developer Pain Index is very high, everyone expects HTML5 to play a savior. Multiple sets of code, different types of technical work, business logic synchronization, this is the process of torturing people. It's a bit like the early world of personal computers, where every computer has its own operating system and programming language, and developers are struggling with different versions, and in fact the popularity of DOS is largely because developers don't have the energy to write programs to other computers. Cross-platform technology in the early years mostly because of performance problems aborted, but in the middle and late hardware capacity will occupy ...
