me of ...NodeI heard that you know Javascript, then I think you should also understand node, at least in the encounter node problem is able to help, if hurriedly can not help, it also at least in-depth study of it: Node file system, stream, server, completely different from the front-end of some development patterns and so on. The back end will only limit the development potential of our front end.Even if your backend doesn't use node in your real pr

Excellent front-end engineers, not overnight, need a lot of learning and accumulation. As a beginner, how to get started, how to choose My Learning route and various tools?1. Before you learn1, do not worry about some complex web page effect code, so in addition to combat your self-confidence, nothing to learn. Did not reach a certain level of martial arts, cut small JJ also learn not sunflower treasure2, do not rush to add technical technology QQ Gro

The topic that we share today is Javascriptqa⼯. See this topic, may be asked: the front end of the development is OK, the rest of the test on the line, where still need to care about these? But in fact, testing is a very important aspect of front-end development, but also the way to advanced front-end engineers! This article is mainly divided into four parts: · Unit Test · Performance testing · Functional Testing · Security testing 　　I. Unit Testing

deeply thought-"There are many technologies, and some technologies will be outdated. What technologies do you refer ?" To some extent, this question can be understood as: What is "ultimate technology? When writing this article, I always think I have written similar articles before. I checked that two years ago, I did say, "What should I learn from software development?" I wrote a blog post for the question. However, in the past two years, I have gained some new benefits. I may take this opportu

, depending on the system load, the CPU can work in multicore/single core, high frequency/ Low-frequency, or switch between FCPU (such as A57) and scpu (such as A53), if the load is lighter, such as off standby, the CPU can switch to LP0, resulting in CPU power consumption approaching 0. The above process involves the following technologies.I. Mechanism of LinuxcpuquiteFor multicore CPUs, running the game requires all core online, browsing the Web page Maybe 1 cores is enough, how to evaluate th

The following is my idea: I do not think that scholars are more advanced than engineers, or that engineers are more sacred, I just think of a person who leads to a great opportunity to become an engineer rather than a scholar based on his psychological traits. I think the engineer must be very fond of comparing his/her own programming, because one of the engineers
