Go tagThe Go program can consist of multiple tags, which can be keywords, identifiers, constants, strings, and symbols. The following GO statement consists of 6 tokens:FMT. Println("Hello, world!" )6 tokens are (one per line):1 . FMT 2 . . 3 .

Recommendation 52: Timely release of resourcesThe garbage collection mechanism automatically reclaims resources for us (the garbage collector calls finalizers automatically), so why should we voluntarily release resources?Private void

Recommendation 148: Do not repeat codeIf duplicate code is found, it means we need to straighten it out and move on.Repetitive code makes our software behave inconsistent. For example, if there are two identical cryptographic codes. As a result, one

Recommendation 143: The method abstraction level should be at the same levelLook at the following code: class SampleClass { publicvoid Init () { /// Local initialization code 1 // Local Initialization code

Recommendation 142: Always provide meaningful namingNever give your code a meaningless name unless you have a special prototype.Afraid of needing too long a name to provide enough meaning? Do not be afraid, in fact, we are more mind is in the code

Recommendation 157: Automate testing from the start of writing the first interfaceIf unit testing is a white-box test, then automated testing is a black-box test. The black box test requires capturing the handle of the control on the interface and

Recommendation 141: Do not know if you should use curly braces.If the IF condition statement has only one line of statements, do you want to use curly braces?The answer is: suggested use. One parenthesis does not add much code, but it makes the code

Recommendation 136: Prioritize using suffixes to indicate new versions of existing typesAdding suffixes in some cases is a very strange form, and we are unwilling to see a type like OrderProcessor2. However, it is still necessary to do so at some

Recommendation 98: Reduce duplicate parameters with paramsIf a method has a variable number of arguments and the parameter type is the same, you can use the params keyword to reduce the duplicate parameter declaration. void Method1
