Rules

More relaxed than regular standard. Code should be enjoyable to write and pretty to look at. A lot of the big ticket items are the same as standard, for example:

• 2 spaces – for indentation
• Single quotes for strings – except to avoid escaping
• No unused variables – this one catches tons of bugs!
• No semicolons
• Never start a line with ( or [
  • This is the only gotcha with omitting semicolons – automatically checked for you!
  • [More details][4]
• Space after keywords if (condition) { ... }
• Space after function name function name (arg) { ... }
• Always use === instead of == – but obj == null is allowed to check null || undefined.
• Always handle the node.js err function parameter
• Always prefix browser globals with window – except document and navigator are okay
  • Prevents accidental use of poorly-named browser globals like open, length, event, and name.
• And [more goodness][5] – give standard a try today!

The biggest differences:

• arrow parens if needed array.filter(x => x) is nicer to look at
• stroustrup brace style down with 1tbs!
• do not force curlys if (bool) doSomething() is nice looking
• proper generator start position - function *sayHello() {}
• line up key colons
• allow case fallthroughs - why disable this feature? Just use if if you don't like it
• no opinion on onevar
