The Supermarket Notes

Here are some notes Brian Boyko is using to swot up for the interview with a supermarket client, but I'm saving it to Github Gist so that maybe others can use it. This is mostly stuff I already knew, but it's been a while since I had to get back-to-basics and remember these as concepts, so I did a bit of swotting up, and took these notes.

The Event Loop

Javascript has a call stack; like any LIFO stack, it only pushes and pops; when a function is called, it pushes onto the stack, when the function is returned, it pops that function off of the stack. This is how the program "keeps track" of where it is; when you see an error message, you'll almost always see a printout of the current call stack.

Javascript was designed as a single-threaded language; it does one thing at a time. This makes it great for simplicity but when you have "slow" functions, like a database call or a network request (which may never resolve), then the entire execution will wait for your slow functions. The b

Vue Extended Styleguide for Vue-Function-API / Vue 3.0 Proposal

Important: This is in the RFC stage. Please comment if you notice typos, code flaws, or even disagree with the conclusions.

I'm still getting used to vue-function-api and haven't had a chance to try it out extensively. In other words, I might be completely wrong on everything. That's okay.

Brian Boyko's Vue.js Style Guide for use with the Vue-Function-API

Guide for developing Vue.js applications for the proposed Vue 3 function API (or the vue-function-api plugin).
