JS semicolons are actually encouraged —omitting them, while syntactically valid, can lead to obscure bugs. http://bonsaiden.github.com/JavaScript-Garden/#core.s

  If you are following Crockford (JavaScript, the Good Parts), it is encouraged. However, some, like the current node.js maintainer think otherwise; see http://blog.izs.me/post/2353458699/an-open-letter-to-javascript-leaders-regarding http://blog.izs.me/post/2353458699/an-open-letter-to-javascr... Personally, I still follow Crockford's advice though.

    And you guys just demonstrated yet another reason why I choose Python for my go-to scripting language. Semicolons are completely redundant in Python and the language is so clean and the style guide PEP 8 is so natural, you rarely hear about these meaningless formatting style bickering in other languages. Saves so much time from arguing.
