first, WebKit kernel and V8In Chrome, use WebKit for HTML rendering, using V8 as the JS engine. Chrome and WebKit are open source, but Chrome keeps webkit distance, and chrome encapsulates a layer called WebKit Glue on WebKit. In the glue layer,

[Longshu Note] introduction to basic concepts involved in syntax analysis This document is my understanding of sections 2.3-2.5 of longshu. It mainly introduces many basic concepts of syntax analysis on the compiler front-end. The next note will be

1. Compiler 1.1. Compile period classificationA *.java file is generally compiled and run, and involves two types of compilation periods:① Compile-time compilation: The process that generally represents *.java->*.class (contains bytecode)-also

PHP7 to the depth of Zend optimization, so that PHP7 speed greatly increased, nearly 5 times times faster than php5.0~5.6, but also reduce the use of PHP system resourcesThe following is a few changes PHP7 than the larger:1, abstract syntax tree:

Are you planning to optimize the Hashcode () method? Do you want to bypass the regular expression? Lukas Eder introduces a number of simple and convenient performance optimization tips as well as extension program performance techniques.Recently,

This article gives you the content is about the new features in the PHP7 summary, there is a certain reference value, the need for a friend can refer to, I hope you have some help. PHP7 has been published to now for nearly three years, and has now

10 simple Java performance optimizations and java performance optimizations Recently, the word "full domain (Web Scale)" has become popular, and people are also scaling their application architecture to make their systems more "full domain ". But

Four Javac compilation processes ?? The Javac compilation process is roughly divided into four processes:Lexical Analysis syntax analysis semantic analysis code generation lexical analysis ?? Lexical analysis is to transform the Token stream of the

ObjectivePrevious "Functional Programming Primer classic", wordy long, many small partners see foggy. Here is an example of how functional programming is fascinating and interesting. Of course, there is no point in writing code just for example, and

The 23 gof design modes are generally divided into three categories: Creation Mode, structure mode, and behavior mode. The Creation Mode abstracts the instantiation process, which helps a system to create, combine, and express its objects

Javac Compilation and JIT compilation compilation Process Whether it's a physical machine or a virtual machine, most of the program code starts with a set of instructions to be compiled into the target code or virtual function of the physical

　　 I. Introduction In fact, there is no good example to introduce the interpreter mode, because it describes how to form a simple language interpreter, mainly used in the use of object-oriented language development compilers; in practical

1 Intent: Given a language, define a representation of its grammar, and define an interpreter that uses that representation to interpret sentences in the language.2 motivation: If a particular type of problem occurs at a sufficiently high frequency,

Lexical analysisLexical analysis converts the character stream of the source code into a set of tokens (tokens), which is the smallest element of the programming process, while the tag is the smallest element of the compilation process, and the
