reading more, we believe that learning Angular 2 in 2017 will be a good investment.
This year we also saw the release of Vue.js 2.0 , which draws on good ideas from Angular,react and Ember, and is lighter and faster than the first two frames. We suggest you try this year and you can start with our vue.js tutorial .
Ember is another good choice for the JavaScript framework. It supports two-way binding of data and the ability to automatically update templates, components, and server-side renderin
faster than the top two.
The other two frameworks worth seeing are Aurelia and react. Last year, react's ecosystems became more complex, making it difficult for beginners to recommend them. But experienced developers can combine libraries with Graphql,relay,flux and immutable.js into a comprehensive, complete stack solution.No front-end compilation can be bypassed BOOTSTRAP,BOOTSTRAP4 is currently in the Alpha version and is expected to be released i
WebThe web platform has recently made two significant advances--web Assembly and Service workers, they open doors to fast and efficient Web applications, bridging the gap with native-compiled applications. Service workers particular, the enabling technology for progressive Web applications (PWA mentioned earlier), and the support for Web platform notifications, will have more APIs in the future.Angular.js 2
Angular.js 2 is released this year. The framework is supported by Google and is very pop

A graphics system typically uses a display as its output device. Most video monitor operations are based on standard cathode ray tube (Cathode-ray tube,crt), but other technologies have emerged, and solid state monitors will eventually dominate. 2.1.1 Refresh type crt[Figure 2.2] Figure 2.2 shows the basic workings of the CRT. The electron beam emitted by an electron gun (cathode rays) is directed at a spec

CRT displays (the scientific name "cathode ray tube") is such a device, it mainly by the electronic gun (electron gun), deflection yoke (deflection coils), shade mask (Shadow mask), high pressure graphite electrode and phosphor coating (phosphor) And the glass shell is composed of five parts. One of the most impressive is the glass shell, also known as a fluorescent screen, because its inner surface can display rich color images and clear text. How do
Raster Scan displayThe normal graphics monitor using the CRT is a TV-based raster scan display (Raster-scan display). In the gratingscanning system, the electron beam transverse scan screen, one line at a time, from top to bottom. Each row is called a scan line ( scanLine ). As the electron beam moves horizontally along each line, the intensity of the electron be

With the rise of HTML5 and the unification of JavaScript, a technology called [cross-platform] is becoming increasingly popular. Why is it so hot? Software developers only need to write a program once to run on Windows, Linux, Mac, IOS, Android, and other platforms. This greatly reduces the workload of programmers and enables fast reading and iteration of the company's products. Previously, cross-platform technology was no

is also an independent system, so it is called a video subsystem. Due to hardware design, the CPU can access the video memory of the video subsystem through the bus, but the display coprocessor cannot access the system memory on the motherboard. However, the speed of the bus is far from enough. When the CPU and display coprocessor perform a large amount of data throughput, the bus becomes abnormal and congested. To solve this problem, the AGP structure is generated. This structure connects the

Update Rate
The refresh rate and the number of frames per second are not confused. FPS indicates how fast your video card can output independent frames per second. The refresh rate is a separate attribute of the CRT display: the number of refresh times per second, no matter how many frames the video card has or what type of images will be displayed on the screen. Most of the t
