React Native Vs Flutter : Ultimate Comparison 2020
Here, we have learned the pros and cons of both frameworks. It is quite difficult to decide which one is the best and there is definitely a strong competition between the two. React Native is the framework that has already made its mark and is continuously growing as well. Flutter is starting to blossom into an amazing mobile application development framework that most developers and companies will turn to in the near future. However, there are still some miles to go. As a matter of fact, the company that already has a JavaScript team for web development will definitely find it easier to transition to React Native the mobile counterpart. Flutter and dart would be new technology better suited for beginners familiar with languages like Java. Hence, both are the potential giants in the world of next-generation mobile applications. React Native has already shown and established its capabilities whereas Flutter is establishing its capabilities.

今天准备的主题叫做“企业级数据可视化应用的机遇与挑战”，偏向于设计体验和工程实现，主要来自于过去这些年自己在这个领域内的一些实践体会和思考，希望作为引子能给大家带来一点灵感或启发。 AntV 是蚂蚁集团的数据可视化解决方案，甚至可以说是整个阿里数据可视化的基础设施，从15年发起至今已经迭代了5年，支撑着集团内外2万+企业级应用。在这些年里我们也走过弯路，踩过很多坑，也逐渐看到些这个领域未来的趋势，所以会有今天想跟大家分享一些我们的实践和思考。
我们在音街移动站中进行了迁移、在多个运营活动中进行了使用，达到了我们预期的目标；在提效方面，埋点库把费时的部分处理了，我们需要做的就是从埋点平台把坑位信息放入配置文件，业务开发的时候使用对应的组件就可以了，几乎没有太大的成本，且对于代码复用和维护来说也达到了目的。 在使用过程中发现对于点击类埋点 appendQueue 使用频率远高于 TrackerClick 组件，因为大部分元素的点击事件都有他自己的回调函数，但是我们使用 TrackerClick 的初衷是埋点代码和业务代码解耦，这个也要根据实际场景去选择。
4 Ways to Communicate Across Browser Tabs in Realtime
Over the years, Web Browser capabilities have ever increased due to the demands coming from web applications. As a result, we can find multiple ways of achieving similar functionality. One such feature we rarely look at is the ability to communicate across Browser Tabs. Let’s look at a few scenarios where you need this.
Whereas Webpack is great for building apps, Rollup is great for building libraries.
For those unfamiliar, a skeleton screen is a method of displaying the outline (skeleton) of the content to come, typically using gray boxes and lines instead of a progress bar while content is loading. It’s a pretty creative approach to handling wait—undoubtedly more creative and helpful than a perpetually spinning circle. But even good ideas can become bad ones if we stray too much from the original intent.
ES2020 Optional Chaining and Dynamic Imports Are Game-Changers. Here’s Why.
Optional Chaining is simply a feature that allows you to safely access deeply nested properties of an object without having to check for the existence of each of them. Optional Chaining uses the ?. operator to access the properties of objects. The usage of the ?. operator is very similar to the typical . operator, but when a reference is undefined or null, rather than throwing an error, it would return undefined.
Dynamic Imports allow you to import JS files dynamically as modules in your application natively. Prior to ES2020, your module should be imported whether the module is used or not. This is a feature that would immensely help improve the performance of your website.

How Web Apps Work: Client Development and Deployment – An overview of the concepts, terms, and data flow used in web apps: JS client development environment, tooling, and deployment https://blog.isquaredsoftware.com/2020/11/how-web-apps-work-client-dev-deployment/_ Web development is a huge field with a vast array of concepts, terms, tools, and technologies. For people just getting started in web dev, this landscape is often bewildering - it’s unclear what most of these pieces are, much less how they fit together. This post provides an overview of fundamental web dev concepts and technologies, what these pieces are, why they’re needed, and how they relate to each other. It’s not a completely exhaustive reference to everything in web development, nor is it a “how to build apps” guide. Instead, it’s a map of the territory, intended to give you a sense of what the landscape looks like, and enough information that you can go research these terms and topics in more depth if needed.
Implementing a Staged Approach to Evolutionary Architecture
Traditionally, software architecture and design phases have been considered as initial phases. In this approach, the architecture decisions were considered valid for the entire life of the system. With the wisdom of ages and in reaction to industry transformations, we have started to see architecture as evolving. This evolution necessitates a different set of approaches in the direction of continuous planning, facilitating via continuous integration, dashboards, and tools, thus providing guide rails for systems to evolve. This article focuses on these approaches and tools to support the journey.

Rockpack - Skip config, code React - Interview with Sergey Aleksandrov
As you might know, configuring webpack isn’t the most fun thing in the world and that’s exactly the reason why I wrote a thick book about it. For many React users, either Create React App (CRA) or framework such as Next.js hides a lot of the complexity. In this interview, we’ll learn about a new solution called Rockpack from its creator Sergey Aleksandrov.**
Back to Basics: Event Delegation
One of my favourite tricks when it comes to building web interfaces is Event Delegation Events don’t just happen on the element you apply them to. Instead they go all the way down the DOM tree to the event and back up again. These phases of the event lifecycle are called event bubbling and event capture.
Comparing Various Ways to Hide Things in CSS
Developers most commonly use display: none to hide the content on the page. Unfortunately, this way of hiding content isn’t bulletproof because now that content is now “inaccessible” to screen readers. It’s tempting to use it, but especially in cases where something is only meant to be visually hidden, don’t reach for it.

Elements that Make a Good Design!
The core purpose of design is to construct a product that will assist the user in achieving a goal with as little friction as possible. Good design is often mistaken for the appealing coordination of colors or the pristine arrangement of components. On a basic level, this distinction reflects two fields involved in designing applications — UX and UI design; which can also be applied to the process of designing physical products.

The Only Step You Need to Progress in Your Career as a Developer or Engineer.
I don’t usually like to write articles about myself, as it feels a bit self-indulgent, but I thought it would be useful to show examples of how I became ‘T’ shaped and how my career progressed. The center of the ‘T’ represents the experience of understanding a particular area of technology or framework. The top part of the ‘T’ refers to an ability to collaborate with experts from other disciplines, gaining even greater understanding and knowledge from this collaboration.
