If you thought the answer was yes, you may want to read on. http://mathiasbynens.be/notes/unquoted-font-family http://mathiasbynens.be/notes/unquoted-font-family#comments http://mathiasbynens.be/notes/unquoted-font-family Tue, 03 Apr 2012 17:38:34 +0200 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? http://mathiasbynens.be/notes/javascript-properties http://mathiasbynens.be/notes/javascript-properties#comments http://mathiasbynens.be/notes/javascript-properties Mon, 05 Mar 2012 21:17:54 +0100 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. http://mathiasbynens.be/notes/javascript-identifiers http://mathiasbynens.be/notes/javascript-identifiers#comments http://mathiasbynens.be/notes/javascript-identifiers Tue, 21 Feb 2012 15:19:15 +0100 Does JavaScript use UCS-2 or UTF-16 encoding? Since I couldn’t find a definitive answer to this question anywhere, I decided to look into it. The answer depends on what you’re referring to: the JavaScript engine, or JavaScript at the language level. http://mathiasbynens.be/notes/javascript-encoding http://mathiasbynens.be/notes/javascript-encoding#comments http://mathiasbynens.be/notes/javascript-encoding Fri, 20 Jan 2012 22:18:54 +0100
