What is V8?V8 is a JavaScript engine developed by Google in the German research and Development center. Open source and implemented in C + +. Can be used for JavaScript programs running on the client and server side.V8 was designed to improve the execution efficiency of JavaScript scripts on browsers. To speed up, V8 translates JavaScript code into more efficient
MotivationJavaScript is a programming language that has the automatic garbage collection feature.In the market has such a function of language, generally have the corresponding virtual machine, like Java's JVM, C # 's CLR, PHP Zend.Virtual machines generally implement code parsing, memory management, layout, garbage collection and other functions.Unlike those languages that do not have a virtual machine, such as C + +, they require manual memory management.The compiled files of the C + + languag
First, browser kernel-rendering engineRendering is the process of building a mathematical model and generating an image based on a description or definition.The main purpose of the browser kernel is to turn the page into a visual/audible multimedia result, often referred to as the rendering engine. Convert html/css/javascript text and other appropriate media type resource files to Web pages.Inside the solid wireframe module is a common part of all porting, and the different vendors in the dashed
Recently, due to busy solving the problem of individual Singles' Day, Chapter 5 was updated after so long.
The previous chapter focuses on the context concept of Google V8. In fact, the basic concepts of Google V8 include functiontemplate and objecttemplate, which will be infiltrated in subsequent chapters.
This chapter mainly describes how to use V8 to implement
1. Context-specific snapshot technologyWhat is context (contexts)? is actually the JS application's operating environment, avoids the application modification mutual influence, for example a page JS modifies the built-in object method ToString, should not affect to another page. Chrome browser Each process has only one instance of the V8 engine, and each window and iframe in the browser corresponds to a context.V8 startup (before executing client JS),
The template is the blueprint of JavaScript Functions and objects in a context.
V8 has two templates:
1. function templates: function template, a blueprint for independent functions. Associate a C ++ callback function with a function template. When a JavaScript function instance is called, it is called.
2. Object Templates: an object template. Each function template has an associated object template. This is used to configure the object created by usi

It is very difficult for a C/C ++ cainiao to study some excellent frameworks, but if they can be imported into xcode projects, compilation and debugging on xode will make it easier to learn this matter. xcode is indeed a powerful tool for developers. Recently, we have been engaged in WebKit, V8, and nodejs. As a result, we have found a way to turn these three frameworks into xcode projects, which is summarized as follows:
