There has already been far too much conversation about whether semicolons are appropriate to use at the end of lines in JavaScript. Serious problems could have been solved in the time JavaScript experts have spent arguing about this. And if the experts can’t make a decision on something as simple as semicolons, what chance do beginners have of understanding JavaScript at all?
Web development is already full of so many variations of ways of doing the same thing, and this is part of what makes our job so much fun - but if you are someone who’s still learning about web development these arguments just makes matters even more confusing.
Often I find myself in a situation where I need to write code for a prototype or proof of concert which will be handed over to another developer. When I write the code I have no idea who that developer is or what their skill level will be.
So my aim has to be to write readable, reusable, consistent code that could be understood by any level of JavaScript developer. Even if they have a fairly basic understanding of JavaScript, they should be able to figure out what is going on. And that includes using semi colons at the end of every line. If you have already written code that is going to take some time to understand, adding further complexity by removing semi-colons from the end of lines isn’t going to help.
And there’s an incentive for me to write readable, understandable code. If I write poorly structured, bad code then I have to spend much longer handing over my code; sitting with the developer; explaining how it works and coming back to answer questions. And I want to work on the next exciting thing. By following an approach that everyone can understand, I’m saving myself time and pain later on.
When you are writing JavaScript, try to stick to best practices and style guidelines such as Rick Waldron’s Idiomatic style guide or Google’s JavaScript style guide, and worry about optimising your code at build time using minification.
Should JavaScript developers know about automatic semi-colon insertion? Sure, it’s good to have an understanding about how it works.. Is it the most important thing for beginners to learn right now? No. Let’s help the newbies by producing code that can be used and understood by all.
And if you are a beginner, then Codecademy is a great place to start learning; and Javascipt: The Good Parts and Eloquent JavaScript should be the top of your reading list.

Shrinkwrap Your Dependencies
Wednesday, February 5 2014
Front end development has evolved over the last couple of years thanks to `npm` popularised by task runners such as Grunt and Gulp. Thanks to our package.json files, it's easy for another developer to get set up on our project in seconds by typing `npm install`. But what happens when some time has passed and your project dependencies have moved on? A new version of a package may introduce a new bug, or completely change its functionality altogether.
Beginning Web Development
Tuesday, January 7 2014
There are so many things to learn in web development now that it can feel incredibly overwhelming - but it can also be very rewarding. What fascinated me about web development was the ability to create - I love to create - and when I started out building web pages I found it incredibly easy to express my creativity with HTML and CSS in just a few lines of code. Here's some tips for if you're just starting out!
jQuery On and Off Namespacing
Tuesday, February 5 2013
Being able to apply and remove events with `on()` and `off()` is great, but sometimes there is a requirement to either trigger or remove a subset of events that have been added to an element. Here's how!

Extending getUserMedia With Canvas
Sunday, July 1 2012
Following on from my previous post which introduced us to getUserMedia, I wanted to share two ways you can extend getUserMedia's video capture using my good friend, the canvas element.
Introduction to getUserMedia
Saturday, June 30 2012
For a long time in the 'Flash vs HTML5' comparison arguments, one advantage Flash had was the ability to capture audio and video from the users computer. With upcoming browser releases, it is now possible to do this with JavaScript and the HTML5 video element, and its very simple to do.
CSS3 Flexbox Carousel
Friday, May 25 2012
Carousels are one of the most common components web developer's build. As other trends come and go, carousels tend to stay.

Scaring Off Beginners

Thoughts on Implementing Responsive Design
Monday, March 19 2012
Responsive design is the latest buzzword in a long series of web buzzwords which has featured 'XML', 'Web 2.0' and 'HTML5' to name a few; but it's one that shouldn't be dismissed.
CSS Regions
Tuesday, March 13 2012
Currently if you have a page where content is separated by a drastic change in layout you will need to include part of your content inside one element, and the other part inside another element. If you're using a CMS, this means you need to have two content fields for what is essentially related content. CSS Columns already offers functionality to separate content in to columns but CSS Regions provide greater control and flexibility of content on your page by allowing content to flow through the page structure, whatever that structure is.
My JS1k 2012 Entry
Monday, February 27 2012
This year I decided to enter the JS1k competition for the first time. The idea behind JS1k is to produce a cool JavaScript application in under 1kb (1024bytes) of code. I had not done any JavaScript golfing before, so I thought it would be a nice little challenge for myself. I didn't realise at the time quite how addictive or time-consuming JavaScript golfing was going to be!
CSS3 Backgrounds of the Future
Monday, February 13 2012
Whilst we've been busy supporting older versions of Internet Explorer, a few new CSS features for backgrounds have sprung out of the woodwork and in to our browsers.
jQuery UK 2012 Conference
Saturday, February 11 2012
Yesterday I travelled to Oxford to attend the jQuery UK conference, which the team at White October carefully crafted together. The snow threatened to stop me, but thankfully calmed down by the morning. So a quick hop, skip and jump on to a train and coach; and I found myself in Oxford at the Saïd Business School.
Modernizr Prefixed
Saturday, February 11 2012
There was a new release of [Modernizr yesterday (2.5.1), and included within this release was some brand new features to the Modernizr Prefixed() API (introduced in 2.0), which can take away some of the pain of vendor prefixes from your JavaScript.
Keeping It Real Simple
Monday, February 6 2012
Last week I had the opportunity to go on a presentation skills course, and one of the tasks we were set was to explain one aspect of our job role to a group of people who had no experience in our field using the LIONS approach using zero jargon.
Impress at Presentations with Impress.js
Tuesday, January 31 2012
The other day I mentioned on Twitter that I was playing around with Bartek Szopka's Impress.js library to write a presentation and it seemed to gather some interest. I then gave the presentation, and that gathered some more interest; so I thought I would write a short blog post about how to use Impress.js.
Writing for the Web
Wednesday, November 30 2011
Today is Blue Beanie Day, an anniversary where developers change their avatars to wear blue beanies to show their support for web standards.

Using jQuery .on() and .off()
Thursday, November 10 2011
With the release of jQuery 1.7 on November 3rd came two new ways to attach event handlers - .on() and .off(). These two additions unify all types of (good) event handling in jQuery and will help you write tidier and more efficient code in the future.
Front End Code Etiquette
Wednesday, November 2 2011
One of the most interesting parts of working as a web developer comes from making a decision on how to organise code depending on a particular project or problem. There are multiple ways to do the same thing, and there's not necessarily a wrong or a right answer for every situation.

Thursday, October 27 2011
