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.

Secondly, the browser has a separate JS debugger, which, however, has only a command line interface, but allows you to do all the basic operations with the code - working with breakpoints, tracing, etc. Working with him is unusual, but if you get used to it, then quite. A list of available commands can be obtained by typing “ help ”, a list of all used JS files and other resources can be obtained by the scripts command , breakpoint management is break , break_info and clean . This is for true console virtuosos.
