Responsible JavaScript: Part I

The web is drowning in a sea of JavaScript, awash with unnecessary bloat, inaccessible cruft, and unsustainable patterns. Jeremy Wagner plots a course to navigate the JavaScript Sea responsibly by building the right things the right way and using the web platform the way it was meant to be used.

Taming Data with JavaScript

Processing huge amounts of data on the web is always a back-end job—except when it’s not. Sometimes processing data in the browser via JavaScript makes sense. What are those use cases, and how can we succeed at them? Brian Greig tells all.

var to JIT

JavaScript language designer Kevin Smith completes the “From URL to Interactive” series. He explains how browsers compile and execute our JavaScript, and what happens from the moment we land on the page to when we leave. Understanding these browser processes leads us to write more performant code.

From URL to Interactive

When we think about it, our whole industry depends on our faith in a handful of “black boxes” few of us fully understand: browsers. We hand over our HTML, CSS, JavaScript, cross our fingers, and hope they render the experience we have in our heads. But knowing how they work can really get you out of a jam when things go wrong. That’s why we’ve assembled a handful of incredibly knowledgeable authors to take us under the hood in this four-part series. Join us on this trip across the web, into the often foggy valley between code and experience.

Coding with Clarity: Part II

Coding with clarity sets great developers apart from the rest. Brandon Gregory shares some principles for organizing objects and functions in JavaScript that will improve clarity, making your code easier to read, understand, and extend.

Fixing Variable Scope Issues with ECMAScript 6

Variable scope in JavaScript has always had its problems. ECMAScript 6 has some features to help developers deal with this and give them more control over their variables. Brandon Gregory gives the low-down on these features and when to use them.

The Cult of the Complex

’Tis a gift to be simple. ALA’s Zeldman bemoans our industry’s current fetish for the needlessly complicated over the straightforward. Escape the cult of the complex! Get back to improving lives, one interaction at a time.

Why Mutation Can Be Scary

Unexpected changes in your JavaScript code can be a real headache. When working with objects, it can be even harder to prevent unintended mutation. Zell Liew shows us some tricks (and libraries) to prevent these unintended changes and ensure stability when working with objects.

My Grandfather’s Travel Logs and Other Repetitive Tasks

When your design project involves unconventional data, how do you structure that data to make manipulating it less tedious? Daniel Warren faced this question when he decided to create an infographic showcasing the decades of extensive travel his grandfather had documented in handwritten journals. Learn about the JavaScript techniques Warren used to minimize repetitive tasks and give his grandfather’s travel logs a new life.

Coding with Clarity

Always writing the clearest possible code is what helps separate the great developers from the merely good. It cuts confusion, reduces headaches for current and future developers, and saves everybody time in the long run. And though not always as easy as it sounds, with good forward planning, a logical approach to code structure, and adherence to a few guiding principles, coding with greater clarity is something all developers can achieve.
