Are there so few keywords in golang?

In the field of programming languages, languages ​​with higher usage rates tend to have powerful features and support libraries. However, for an emerging programming language - Golang, people found that the number of keywords is not only small, but also surprisingly simple. This situation must have aroused the curiosity of many programmers.

Golang is an open source programming language launched by Google, also known as Go. As a modern language, Golang's design goal is to provide a simple, efficient, safe and reliable programming environment. To this end, Golang adopts a unique syntax structure that makes it very different from other programming languages.

In the grammatical structure of Golang, we can find that there are only 25 keywords, including 18 reserved keywords and 7 dependent packages. This number is indeed much less than other programming languages. However, let's take a look at why these keywords are enough to support Golang's powerful performance and rapid development capabilities.

The first is reserved keywords. Golang’s 18 reserved keywords include the basic control structures if, else, for, and switch; there are also keywords func, defer, go, and return that define functions; there are also type declaration keywords; variable declaration keys The word var; the constant declaration keyword const; the pointer keyword *; the slice keyword []; the structure keyword struct, etc.

These keywords are sufficient to support the basic semantics of Golang and are also very intuitive. For example, we can implement various control structures through loop keywords such as if, else, and for. At the same time, the function definition in Golang is also very concise. You can define a function using the keyword func.

In addition, Golang also uses a very concise but powerful type declaration, allowing developers to define and declare types more efficiently. For example, we can use the type keyword to define aliases of any type, and use the type keyword to define structure types, function types, interface types, etc.

In addition to reserved keywords, Golang also has 7 keywords for importing packages, namely import, ., _, alias, package, const and var. These keywords support Golang's modular design and the import of external libraries.

In general, the reason why Golang has fewer keywords than other programming languages ​​is because its designers pursued a simple and powerful language style. At the same time, Golang's grammatical structure also allows it to be developed more efficiently, which is one of the reasons why it is popular in fields such as cloud computing and data science.

However, the use of Golang still needs to be continuously explored and optimized in actual development. For more complex programs, other languages ​​or frameworks may need to be used to supplement them. In short, Golang can still provide a simple and efficient programming environment even with a small number of keywords, which is an important reason for its appeal.
