(As more sites follow this practice, more users already have the file ready.) It ensures that the payload will be as … Read more
Update based on comments: Short version: It doesn’t matter much, but it may depend on what they host. They all host different things: Google doesn’t host jQuery.Validate, Microsoft did not host jQuery-UI, since 2016 they do!!, Microsoft offers their scripts that would otherwise be served via ScriptResource.axd and an easier integration (e.g. ScriptManager with ASP.Net … Read more
If you NPM those modules you can serve them using static redirect. First install the packages: npm install jquery npm install bootstrap Then on the server.js: var express = require(‘express’); var app = express(); // prepare server app.use(‘/api’, api); // redirect API calls app.use(“https://stackoverflow.com/”, express.static(__dirname + ‘/www’)); // redirect root app.use(‘/js’, express.static(__dirname + ‘/node_modules/bootstrap/dist/js’)); // … Read more

One more reason to not use Google-hosted jQuery is that in some countries, Google’s domain name … Read more
