create topologies. New components are often done in an interface way. In contrast, declarative API operations are defined higher-order functions. It allows us to write function code with abstract types and methods, and the system creates the topology and optimizes the topology. Declarative APIs often also provide more advanced operations (such as window functions or state management). The sample code will be given shortly after.

The first is to introduce a concept-typesetting engine (layout engine,rendering), which is the browser kernel that most people who surf the internet may have heard of, and are responsible for parsing page syntax (such as HTML, JavaScript) and rendering, Display Web pages . the core of each brand browser is different, and different cores have different ideas when dealing with the same piece of code. So it can be said that the difference between the browser cores is the root cause of the compatibi

Each organization has at least one browser product that uses its own kernel.The four organizations are Microsoft, Mozilla, Apple and opera SAS, with the kernel being called Trident, Gecko, WebKit, and Presto, with the launch of a flagship browser called Internet Explorer, Firefox, Safari, and opera.People often use the name of the main browser instead
