Use of Vue2.0 series filters and vue2.0 series Filters
Vue2.0 has deprecated the filter and requires a custom filter for common text formatting.
It feels super easy to use !!
The filter can be used in two places: Double curly brackets interpolation and v-bind expressions.
The filter should be added at the end of the JavaScript expression, indicated by the pipeline operator.
1. Register a global Filter

Follow the steps in the previous chapter. In the previous chapter, we mainly explain some knowledge points about user requests, resolution requests, server feedback requests, and sessions, it is inevitable that you will encounter some problems, such as database query failure, Script Error Caused by user input, network problems,
external engine load, it is easiest to make memcached parallel control (concurrency control), but for the engine, parallel controls are the true essence of performance, so we have adopted a design that gives the multithreading support to the engine completely.Future improvements will make the memcached more widely used.SummarizeThis paper introduces the time-out principle of memcached, how to delete data inside, and then introduces the newest development direction of memcached such as binary pr

First of all, from the point of view of time can be a series of basically divided into 3 categories:
1. Pure random sequence (white noise sequence), this time can stop the analysis, because it is like predicting the next coin which side is as irregular as possible.
2. Stationary non-white noise sequences , whose mean and variance are constants, for such sequences, there are mature models to fit the future development of this sequence, such as Ar,ma,ar
Programmers must have been familiar with the "Fibonacci series" and "Joseph's ring". The two types of code here do not mean different experiences. Instead, find the method. This is what we call the data structure and algorithm. The Foundation is very important, so I don't want to chase PHP's gorgeous functions.
F (n) = f (n-1) + f (n-2) F (1) = 1 F (2) = 1 PHP code:
