problems, to intermediate and more engineers are more than the language of the majority, Take a different approach to solving the problem in the application scenario It can be concluded that the market is now more expected to Golang is medium-high, senior, senior talent, but a little bit less intermediate We can try to hit the impact again. 3.

Channel and lock who light weight? A word tells you: the channel itself is implemented with a lock. As a result, it is necessary to minimize the use of channel, but the channel is supported by the language layer, moderate use, can improve the code can read and write Reprint Please specify: War Soul small Build Http://www.cppblog.com/sunicdavy Error Think Golang constantly handling err? That is because in other languages do not deal with errors at all

Today the sky just lit up, get up to see Golang 1.11 official release, with two important features: modules and webassembly. This blog as long as the Modules,congjava turn Golang classmate is certainly the Golang package management is full of frustration, I have also introduced glide in the blog, and introduced DEP, and now we upgrade the

Golang basics and golang Basics1. Inheritance overload is not supported. For example, for C ++ Java interfaces, modification of interfaces will affect the modification of class behavior of the entire interface to be modified. Go designers think this feature may be useless. 2. Any function definition must be followed by curly brackets after the function declaration and cannot be wrapped in a line break such

If you are interested in Golang but have not yet begun to get started, this article is for you. Why do you learn Golang? Many of the articles lobbying developers to try Golang.For example, a speech by Golang's main designer, a German spat, a preface to a book by a domestic Golang preacher. I do not want to repeat Daniel's point of view, just to talk about their

function can only be returned by the EAX register to the calling function, so the C + + function can only return a value, So is it possible to imagine that Golang multivalued returns can be achieved through multiple registers, just as with multiple registers to pass the argument? This is also a method, but Golang is not adopted; My understanding is that the introducti
