Message from JavaScript talks

— It is not only a matter of preference rather it mostly depends upon what are the requirements


Each page of the app should be in it's own persistent document fragment, then you can change it, then clone it into a DOM node and bam, that is the fastest possible way to interact with the page in js


var myPage = document.createDocumentFragment();
var myContainer = myPage.createElement("div");

this creates a blazing fast docfrag that doesn't exist in the DOM, it gets changed extremely quickly, except this can be very cumbersome to write yourself so I reccomend a premade lib or framework to take some of the load off

— That is a virtual DOM by definition

— No react required

— A docfrag is literally the same principles as react's virtual dom, even

— I'll try to explain with situations which I face daily, we use Symfony in our company and we have created custom form types in Symfony using Twig and AngularJS, these form types are basically reusable components which do a lot of work from helping in generation of views to ajax requests. We just write one line of code to do all this stuff.

— And comes with js

— Nice, I love component based systems like that

— So basically here scalability and reusability comes at cost of speed ( not that much though ) but it saves us ( devs) a lot of hours in which we can do other works

— Disagree, compute is cheap

— And "performance is everything" and posting PHP snippets a few messages later is kinda... yeah, no
