Author Kathy Sierra says the question isn’t what do you have to know to be a Web developer; it’s how quickly can you learn and build skills. “Expertise,” says Sierra, “requires cognitive resource management.” The reason why some people just can’t make progress, she says, “is there are just too many things draining their cognitive resources.” See more signals from the O'Reilly Fluent Conference...
Enabling the creation of maintainable sites and apps that look great across a variety of different devices and contexts.
Choose your Learning Path. Our new Learning Paths will help you get where you want to go, whether it’s learning a programming language, developing new skills, or getting started with something entirely new.
CSS’ declarative model can be uniquely efficient, but requires an understanding not only of the features you want to use but the approach you want to take in decorating a document tree. That means understanding the document tree (and there may be many variations as you apply the same style sheet to multiple documents), the selectors used to identify points on the tree, the cascade that resolves conflicts among selectors, and the properties applied to that tree. Of course, the properties interact with each other and a shared model, so you’ll need to understand how the properties how to make those interactions produce your vision.
:focus'ing on users.
Editor’s note: The author would like to acknowledge her co-author, Brian Kardell, who contributed many insights to the ideas presented here, along with a substantial number of the words.
Web developers and web standards authors alike strive to live up to the promise of “universality” — the idea that the web should be available to all. This concept drives many innovations in web technology, as well as being fundamentally built in to the philosophy of the open standards on which the web is based.
In order to achieve this, we frequently find that having some carefully chosen information about how the user intends to view the content (a concept we’ll refer to in this article as “user context”) allows web developers to create more flexible and useful user experiences. In this post, we’ll lay out a case that it’s time to expand our view of user context to include the concept of modality (how the user is interacting with the page), but before we flesh that out, let’s take a look at “user context”.
Access not just to content, but technology.
“They learn a bit of Web stuff, and the next thing you know they think they understand programming.” I’ve heard variations of that lament for the past two decades. I’ve heard it less lately, because so many recent computing professionals built their technical careers from that bit of Web stuff.
The Web succeeded in large part because it was the easiest way for people to create electronic content and share it. Indexes and search engines made it easier to find that content. While administering files on a server and learning HTML weren’t trivial, they were much more approachable tasks than creating and distributing traditional (now largely considered desktop or native) applications.
For the most part, they still are easier.
WebAssembly – wasm – skips that final step, producing a binary format, technically a compressed AST encoding. Unless you’re going to be building compilers, you can compare wasm to a bytecode system. There is a text format for debugging, but the binary emphasis yields substantial extra speed as it skips parsing and minimizes decompression.
Raising the banner for a new discipline.
In this excerpt taken from the upcoming book, Front-End Architecture: A Modern Blueprint for Scalable and Sustainable Design Systems, Micah Godbolt details the history of this new discipline and explains why it is such a vital role to embrace in our industry.
With the evolution of the web came changes to the roles of the modern web team. We went from a small group of generalist webmasters to a team of talented specialists. As each of these specialties developed, and members became more proficient in them, the web began to form a new set of roles… or disciplines.
