Should I use use express or switch to javascript and html? -

i have been building web application takes user input , after doing modifies files on server side. core logic of build in node.js , works through command line, of site build using javascript , html.

i've read using express easier in conjunction node modify server-side files. enough reason switch or should revamp code in regular javascript?

pd: i'm new , first web application

express javascript. library; codebase can more , write less. recommend it, if first web app.

it important, general rule, don't learn express. because can use express , nothing else doesn't mean should. challenge learn inner workings of how framework things, , how web apps, regular apps, work.

having knowledge make easier in long run, isn't should reinvent wheel.

overall, use express, make sure know how on own.
