What is the core of language?

Recently, I encountered the core word of the programming language, so I made some simple analysis and understanding about it.

The core of natural language is the definition of natural language, that is, the definition of words, words, sentences and paragraphs and the interpretation of words, words, sentences and paragraphs. Similarly, the core of a computer programming language is our definition based on a computer system, such as the definition of data types, keywords, operators, and functions.

With the definition of a computer programming language, you can use the language to write articles after you are familiar with the syntax of the language. This is the compilation of applications. How to make the computer understand the application is the work of the compiler. the compiler is actually a system program that remembers the definition of the computer language and translates the application through the memory.

Sometimes, in order to improve our writing speed or enrich the content of the article, we will directly reference the content written by others, which may be completed simply in this language, alternatively, you can use this language to encapsulate the content written in other or lower-layer languages (for example, an API encapsulated by system calls provided by the operating system ). The referenced content is actually a supplement to the computer language, that is, the library.
