pluck(propertyName) -> Array

Optimization for a common use-case of collect: fetching the same property for all the elements. Returns the property values.

Since it avoids the cost of a lexical closure over an anonymous function (like you would do with collect), this performs much better.

Perhaps more importantly, it definitely makes for more concise and more readable source code.


['hello', 'world', 'this', 'is', 'nice'].pluck('length')
// -> [5, 5, 4, 3, 4]

// -> sorted list of unique canonical tag names for elements with this
// specific CSS class...
