What does \u003C mean?
JavascriptJavascript Problem Overview
I'm looking at twitter's javascript file, and I see this in the templates hash:
Browse Interests{{/i}}\u003C/a\u003E\n \u003C/li\u003E\n {{#logged_in}}\n
What do those codes represent?
Javascript Solutions
Solution 1 - Javascript
It's a unicode character. In this case \u003C and \u003E mean :
> U+003C < Less-than sign > > U+003E > Greater-than sign
See a list here
Solution 2 - Javascript
That is a unicode character code that, when parsed by JavaScript as a string, is converted into its corresponding character (JavaScript automatically converts any occurrences of \uXXXX into the corresponding Unicode character). For example, your example would be:
Browse Interests{{/i}}</a>\n </li>\n {{#logged_in}}\n
As you can see, \u003C changes into < (less-than sign) and \u003E changes into > (greater-than sign).
In addition to the link posted by Raynos, this page from the Unicode website lists a lot of characters (so many that they decided to annoyingly group them) and this page has a (kind of) nice index.
Solution 3 - Javascript
It is a unicode char \u003C = <
Solution 4 - Javascript
Those are unicode escapes. The general unicode escapes looks like \uxxxx where xxxx are the hexadecimal digits of the ASCI characters. They are used mainly to insert special characters inside a javascript string.
Solution 5 - Javascript
Unicode all starts with \u e.g. \u0001
Solution 6 - Javascript
In JavaScript
unescape("\u003c")
to decode the unicode

Although unescape() is not strictly deprecated (as in "removed from the Web standards")
