The colon quickly shifted the topic: "Let's talk about declarative programming relative to imperative programming (declarative programming)." As the name implies, declarative programming consists of a number of specification (specification) declarations, a series of statements: ' Know this, solve that ', and emphasize ' what to do ' rather than ' how '. Declarative programming is the abstraction of the human brain's way of thinking, that is, the use of mathematical logic or established norms for the inference or operation of known conditions. ”
