What is go language

Go language is a statically strongly typed, compiled language, and its syntax is similar to C language. Go language stipulates that there is no need to write a semicolon after the end of each line of program, braces cannot be placed on a new line, and if judgments and for loops do not need to be wrapped in parentheses.

Detailed introduction:

Go (also known as Golang) is the work of Robert Griesemer, Rob Pike and A statically strongly typed, compiled language developed by Ken Thompson. The Go language syntax is similar to C, but its functions include: memory safety, GC (garbage collection), structural form and CSP-style concurrent computing.

Go's syntax is close to C language, but the declaration of variables is different. Go supports garbage collection. Go's parallel model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages ​​that adopt a similar model include Occam and Limbo, but it also has features of Pi operations, such as channel transmission. Plugin support is opened in version 1.8, which means that some functions can now be dynamically loaded from Go.

Compared with C, Go does not include functions such as enumeration, exception handling, inheritance, generics, assertions, virtual functions, etc., but it adds slice type, concurrency, pipes, garbage collection, Language-level support for features such as interfaces. The Go 2.0 version will support generics, but has a negative attitude towards the existence of assertions, and also defends that it does not provide type inheritance.

Unlike Java, Go has built-in associative arrays (also known as hash tables (Hashes) or dictionaries (Dictionaries)), just like string types.

Writing style:

There are several regulations in Go. When the following regulations are not matched, compilation will produce an error.

There is no need to write a semicolon (;) after each line of the program.

Braces ({) cannot be placed on new lines.

If judgments and for loops do not need to be wrapped in parentheses.

Go also has a built-in gofmt tool, which can automatically sort out excess whitespace in the code, align variable names, and convert aligned spaces into tabs.
