. JS Web application is to build a basic server. So let's look at the similarities and differences when building a server with these frameworks.3.1 Expressvar express = require(‘express‘);var app = express(); var server = app.listen(3000, function() { console.log(‘Express is listening to http://localhost:3000‘); });For all node developers, this looks pretty natural. We put express require in, then initi

-type number because it does not provide a piece of memory to store array-type numbers.This is a bit confusing. Note that numbers do not have to be stored in the memory. For long a [3] = {45, 45, 45};, assume that the number mapped to a is 3000, it indicates that the number recorded in memory unit 3000 is interpreted according to the rule of long [3]. The length of this number is 3 * sizeof (long) = 12 byte
