By default, only the html and the body element (plus its children) of a web page are actually rendered. All information within the head element might be parsed and used by the browser, but most of the time it doesn’t get displayed. If you want to, you can use CSS to display these ‘hidden’ elements.

One of the lesser known HTML5 JavaScript goodies is the document.head DOM tree accessor, which is a more efficient (and easier to type) alternative to document.getElementsByTagName('head')[0]. Native support for document.head is very easy to detect…

A few days ago, Martín Borthiry contacted me with a question. He had been using the optimized asynchronous Google Analytics snippet for a while, and noticed an additional speed gain when wrapping it inside a setTimeout() with a delay of 0 milliseconds. His tests made it pretty clear that this technique was indeed slightly faster, but Martín had no clue why.

Recently, a popular new addition was made to the HTML spec: anchors may now have a download attribute. That’s not what this post is about though — instead, I’d like to go over some of the different notations people used to refer to this new element + attribute combo in tweets and blog posts.

I thought it would be fun to document the smallest possible valid HTML documents for each version, so here goes :)

Did you know var π = Math.PI; is syntactically valid JavaScript? I thought this was pretty cool, so I decided to look into which Unicode glyphs are allowed in JavaScript variable names, or identifiers as the ECMAScript specification calls them.

Fun fact: var foo = { H̹̙̦̮͉̩̗̗ͧ̇̏̊̾Eͨ͆͒̆ͮ̃͏̷̮̣̫̤̣Cͯ̂͐͏̨̛͔̦̟͈̻O̜͎͍͙͚̬̝̣̽ͮ͐͗̀ͤ̍̀͢M̴̡̲̭͍͇̼̟̯̦̉̒͠Ḛ̛̙̞̪̗ͥͤͩ̾͑̔͐ͅṮ̴̷̷̗̼͍̿̿̓̽͐H̙̙̔̄͜: 42 }; is valid JavaScript. It may not be immediately obvious, but the real surprise here is that the Cthulhu-esque property name is not surrounded by quotes. Intrigued by this, and having written about the similar topic of JavaScript identifiers before, I decided to look into valid property names in JavaScript. When do they need to be quoted? When can the quotes be omitted? And in which cases can dot notation be used instead of bracket notation to get or set a property based on its name?

Are the quotes in font-family: 'Comic Sans MS' required, or not? If you thought the answer was yes, you may want to read on.

ES2015 updates the grammar for identifiers. This affects a number of things, but most importantly, identifiers can be used as variable names, and identifier names are valid unquoted property names. This post describes the observable changes compared to the old ES5 behavior.
