Before two weeks ago or so, it used to be Backbone views and models, and everything was on our main store app, and our mobile web app, but actually, we just switched our mobile web app to using ReactJS for the interface. So it’s using Backbone models but ReactJS front-end components. Really, it was borne out of the frustration with how the Backbone model-view bindings worked, and it wasn’t especially performant for large views, and we had to do lots of tricks to make it performant. But swapping that out with React views meant that it could be both simpler and faster without having to spend a lot of time on that.

One other interesting thing about that is, since React actually works okay with the Backbone models and the Backbone router and stuff like that, we didn’t have to rewrite the mobile web application and update it to ReactJS. Rewrites are almost always a bad idea. We were able to upgrade pieces of it at a time, move on to React, and now the entire thing is using React and just has the Backbone router and models and stuff like that that we already had, so it's a lot faster.

At the beginning of last year, Netflix UI engineers embarked on several ambitious projects to dramatically transform the user experience on our desktop and mobile platforms. Given a UI redesign of a scale similar to that undergone by TVs and game consoles, it was essential for us to re-evaluate our existing UI technology stack and to determine whether to explore new solutions. Do we have the right building blocks to create best-in-class single-page web applications? And what specific problems are we looking to solve? Much of our existing front-end infrastructure consists of hand-rolled components optimized for the current website and iOS application. Our decision to adopt React was influenced by a number of factors, most notably: 1) startup speed, 2) runtime performance, and 3) modularity.

React has exceeded our requirements and enabled us to build a tremendous foundation on which to innovate the Netflix experience.

Web-frontend programming prior to React: like banging rocks together. With React: Like wearing fusion powered underwear. Gives you a nice warm feeling. Using React for Cloudcraft.co allowed us to create a beautiful UI in record time (1 month start to launch), with virtually no bugs popping up during development. The functional approach to just rendering your component given a state just makes so much sense, with React figuring out the delta between your current and desired representation. It's the future kids!

React is choice number 1 when it comes to JS development at Kurzor. We choose React because it solves many issues with web applications in a elegant way. Writing an app in components is useful for coordination and isolation of concerns. React forces you to abandon state and use vertical passing through props instead. And having as many Pure Components as possible helps to write cleaner code.

With React we usually use: Redux, React Router, React Toolbox, Styled Components.

jQuery has been the basis of our front end JS for a number of years. The key part for us was that the amount of code saved by using jQuery methods, as opposed to writing out cross-browser compatible alternatives made it a no brainer. In recent years we've had to be clever in how we deliver jQuery on the websites, to ensure it's not render blocking and improve client-side performance but it's still a vital library.

jQuery allows to easily do DOM scripting (i.e. HTML elements manipulation and event handling). using jquery under MVC webapps. Studing to know more

This is the best component framework and API available today for building modern web sites and apps. I really enjoy how minimal it is, and powerful at the same time. It removes opinionated development and replaces it with logic and data philosophies, which has in turn fostered a robust and lively code and support community.

It is used widely to build client side applications. It is equipped with attractive features such as event handling, Ajax calls, animations and allow the developer to create new plugins on top of JQuery. This tool frequently uses for building JavaScript web development solutions.

jQuery is only used in small amounts, primarily for animations and UIs, but it is included in the WSC, so we felt like not including it here would be kind of cheating. jQuery also almost makes ajax-requests a pleasure to work with, so ... you got that point, jQuery.

I don't use javascript, I use jquery....well I know it does not make sense, but I just want to stress how important it is. let's rephase it: whenever I use javascript, I use jquery. when you look at any js file of mine, 90% is jqery api.
