React:react provides an easy way to create complex management and data-intensive apps. It is also very fast because the virtual DOM is one of React's USP. It can be said that React Native has consolidated the status of React as the authoritative front-end Java library, making it easy to build cross-platform.
Angular: It's a fully fledged framework, and it has more tool kits than React. And because it was created by Google, you can be confident that it alway

Preface
At the end of the article "Code Runaway and state machine", we left a "job" that resolves the "Member access expression", so we can do this work together.
First of all, why do you want to write a parser that looks useless? Because in some IOC or AOP container (unfortunately I need to implement an IOC container), it is often necessary to dynamically solve the value of a member access expression, and parsing an expression is the first step. In fact, this "job" is the compiler technology m
Every technical expert in the JAVA/JVM field should benefit from those projects, with 2011 of them nominated for the Best Technology Product Award at the Jax Conference held in Sanjose. I chose them because they can be used extensively in a range of projects to solve real-world problems. As a developer, we have to talk about this every day, so let's take a quick look at some exciting projects.0. NEO4J Graphics DatabaseNEO4J is a high-performance graph

Earlier than 12306, it adopted the Unix minicomputer architecture and transformed it into a Linux/X86 server cluster architecture using GemFire technology, it means that it spans three generations. From minicomputers to large memory X86 server clusters, this not only improves the performance by an order of magnitude, but
terabytes of data can be loaded into the memory for memory computing. The computing process itself does not need to read or write data to the disk, but regularly writes data to the disk in synchronous or asynchronous mode. Gemfire stores multiple copies of data in a distributed cluster. If one machine fails and other machines have backup data, you do not have to worry about data loss and have disk data as a backup.

Abstract: Almost all software project development needs the support of the database, at present, with the rapid development of open source technology, more and more data suppliers choose Open Source database, contribute to the cause of open source.
As a software developer or DBA, one of the essential tasks is to deal with databases, such as MS SQL Server, MySQL, Oracle, PostgreSQL, MongoDB, and so on. As we all know, MySQL is currently the most widely used and the best free open source database
