“You’ll never believe where objects come from in JavaScript.”


“These 10 languages are worse than JavaScript in asynchronous programming.”


Let’s explore some aspects of JavaScript that you might take for granted in the clickbaitest nodecongress.com workshop.


To attend this workshop you only need to be able to write and run NodeJS code on your computer. Both junior and senior developers are welcome.


Objects are from Mars, functions are from Venus


Let’s deep-dive into the ins and outs of objects and then zoom out to see modules from a different perspective. How many ways are there to create objects? Are they all that useful? When should you consider using them?


If you’re now thinking “who cares?“, then this workshop is probably for you.


Asynchronous JavaScript: the good? parts


Let’s have an honest conversation.


I mean… why, oh why, do we need to bear with all this BS? My guess is that it depends on perspective too. Let’s first assume a hard truth about it: it could be worse… then maybe we can start seeing the not-so-bad-even-great features of JavaScript regarding non-blocking programs.

This workshop has been presented at Node Congress 2022, check out the latest edition of this JavaScript Conference.

JavaScript handles asynchronous behavior through callback functions and the Promise API, which includes methods like .then, .catch, .all, and .race.

The module pattern in JavaScript uses functions to create a local scope for variables and functions, allowing for encapsulation and private variables. This pattern is useful for creating single instances or services.

Yes, there will be a recording of this session, and the organization will make it accessible.

The workshop focuses on basic principles and patterns, specifically objects and asynchronous behavior in Node.js.

The Promise API in JavaScript helps manage asynchronous operations by allowing you to chain callbacks, handle errors, and coordinate multiple operations with methods like .then, .catch, .all, and .race.

You can create objects using object literals, classes, and the module pattern. Object.create and Object.assign are also advanced methods.

The prototype chain in JavaScript is a series of linked objects that allows properties and methods to be inherited from other objects. It starts from the object's __proto__ property and ends with a null value.

Using a library might seem easy at first glance, but how do you choose the right library? How do you upgrade an existing one? And how do you wade through the documentation to find what you want?
In this workshop, we’ll discuss all these finer points while going through a general example of building a code editor using CodeMirror in React. All while sharing some of the nuances our team learned about using this library and some problems we encountered.

Making JavaScript on WebAssembly Fast
Top Content
WebAssembly enables optimizing JavaScript performance for different environments by deploying the JavaScript engine as a portable WebAssembly module. By making JavaScript on WebAssembly fast, instances can be created for each request, reducing latency and security risks. Initialization and runtime phases can be improved with tools like Wiser and snapshotting, resulting in faster startup times. Optimizing JavaScript performance in WebAssembly can be achieved through techniques like ahead-of-time compilation and inline caching. WebAssembly usage is growing outside the web, offering benefits like isolation and portability. Build sizes and snapshotting in WebAssembly depend on the application, and more information can be found on the Mozilla Hacks website and Bike Reliance site.

Webpack in 5 Years?
Top Content
In the last 10 years, Webpack has shaped the way we develop web applications by introducing code splitting, co-locating style sheets and assets with JavaScript modules, and enabling bundling for server-side processing. Webpack's flexibility and large plugin system have also contributed to innovation in the ecosystem. The initial configuration for Webpack can be overwhelming, but it is necessary due to the complexity of modern web applications. In larger scale applications, there are performance problems in Webpack due to issues with garbage collection, leveraging multiple CPUs, and architectural limitations. Fixing problems in Webpack has trade-offs, but a rewrite could optimize architecture and fix performance issues.
