A lot of new coders struggle with understanding with http request/response and I spent the last few days t writing an article to see if I could explain this using an analogy as well as explain the basics of scaling a web app.Can folks at the Hacker News community please provide some feedback? Would you agree with this approach? Any advice/recommendation on the analogy or other areas you think...
If you want to hone your javascript, try a module I've created where I am trying to get people to quickly improve their JS skills (to where they can understand concepts such as callback, closure, arrow functions, ES5/ES6 syntaxes, etc): https://www.hackerhero.com/g/advanced-javascript-beta
Once you master these skills, then if you study React, I think a lot more jobs will open up for you. You can also use your updated JS language to learn Node.js and get familiar with Express. Also study socket.io to really study how socket is used, especially for building real time web applications.
Also beef up your resume by studying other tools such as LESS, SASS, Coffeescript, Typescript (and spend no more than a few hours on each of them). Beefing up your resume with more modern libraries will distinguish your resume from other resume that also state they know HTML, CSS, and jQuery.
Hope this helps.
