building closures-function expressions. function Sandwichmaker (magicingredient) { return function (filling) { Return magicingredient+ "and" +filling; } } Note that the function expression is anonymous. Because only a new value needs to be generated and not used locally, it is not necessary to name the function.Third fact: Closures can update the values of external variables.In fact, closures store references to external variables, not copies of their values. So an

Redis has always been a component that I want to study well, but previously limited to work scenarios that didn't really make sense to use. But at the moment, Redis acts as the primary cache component to buffer server pressure. Therefore, this sequence is mainly based on the actual work encountered in the design and development of the redis, and gradually, in order to be rational, there is no misleading anyone.Before I begin, I will share the relevant content mainly from the following points:1.
