DOM Performance

• How the browser renders the document
  • Receives the data (bytes) from the server.
  • Parses and converts into tokens (<, TagName, Attribute, AttributeValue, >).
  • Turns tokens into nodes.
  • Turns nodes into the DOM tree.
• Builds CSSOM tree from the css rules.

Full socket.io client and server example

Last updated: 2021-02-21, tested with socket.io v3.1.1

This is the simplest implementation you will find for a client/server WebSockets architecture using socket.io.

To see a full explanation, read my answer on SO here: https://stackoverflow.com/a/24232050/778272.

If you're looking for examples using frameworks, check these links:

Project Ideas

Ok. I'm going to list off some ideas for projects. You will have to determine if any particular idea is good enough to include in a portfolio. These aren't creative ideas. They likely already exist. Some are way too advanced while others are simplistic.

I will recommend to post any project you make to github and make a github project page for it. Explain in as much detail as possible how you made it, how it can be improved etc. Document it.

If you pick an advanced idea, setup a development roadmap and follow it. This will show some project management skills.

Another piece of advice for those who are design challenged. Use different front end frameworks and use different themes for those frameworks to provide appealing designs without looking like yet another bootstrap site.

lodash/fp - set / flow

In this gist we are going to learn about basic goodies that we get from the library lodash/fp (fp stands for functional programming, great for ensuring immutability).We'll learn just by doing (step by step guided sample + codepens).

We'll cover lodash set and flow functions

Steps

• We'll use codepen as our playground, navigate to this page:
