Факт о медицине:
JavaScript is handled by the new V8 engine , which is also open source and is fast and efficient in memory management. V8 is available in source codes for all platforms (written in C ++), and can be built as a standalone application or embedded in others (for more details , see the documentation). The main advantage of the engine is faster access to object fields (in principle, it can be implemented with just one instruction), as well as the rejection of intermediate code transformations, JavaScript is translated at the first call immediately into machine code (as I understand it, into assembler). The last trump card is the built-in garbage collector, which allows you to save memory, which is especially true for complex and large JS applications. This all sounds like a description of the ideal engine, but the war on this front is just beginning, because Firefox 3.1 should also handle JS code better, and in fact, as far as I know, the next generation Tamarin engine is not even used yet.

All browser components are connected into one whole system using the interprocess communication protocol (IPC) based on the name pipe. This is an independent and large topic, described in detail in the documentation . standard streams ( more about the stream model). It is this architecture that allows the browser to demonstrate amazing speed even when several dozens of tabs are open in parallel, including those with resource-intensive applications. However, the reverse side of the coin is a fairly large memory consumption, although in light of the fact that even budget laptops are equipped with 1 GB of memory, this is not so significant.
