In the development of the program we will assume that the external provided interface or data is not trustworthy. For example, the function is always to check the correctness of the parameters, in the unit test to the external interface provided by the shield off and so on. It's hard to make sure that you or someone else can provide an interface without any flaws. Since the interface is written by people, then there is a little bit of thinking about it, and when the interface is called, it is po

Whether it is an array (arrary) or a linked list (list), it is indispensable in programming. Golang also has arrays, unlike other languages, Golang also provides slices (slice). Slices have better flexibility than arrays and have some dynamic chara

this in the Golang has been a strong guarantee. Golang at the language level (or more rationally at the compiler tool level) prescribes a developer's directory structure and the geographic location of various files, and this management is inherently responsive to the idea of open source and caters to git, Mercury's management model.

Many programmers are accustomed to seeing all anomalies as errors, without distinguishing between errors and exceptions, and, even if exceptions are thrown in the program, they are caught and converted into errors in a timely manner. On the surface, the idea of everything being wrong is simpler, and the introduction of exception

DEP Golang Package Management usage Records DEP is one of the Golang project dependency management, is an official experimental project, the current update is very frequent in the high-speed development period, so the choice of DEP as a Golang dependency manager is more reliable.

[TOC] "Recorded in February 2018" The concept of reflection in programming languages In computer science, reflection refers to a class of applications that are self-describing and self-controlling. In other words, this kind of application uses some mechanism to realize the description (self-representation) and monitoring (examination) of its own behavior, and can adjust or modify the state and related semantics of
