Simplest code to sort arrays in ruby?

Question

I usually do something like

Click to copy

array.sort{|a,b| a.something <=> b.something}

How should I DRY this up?

Answer 1

use sort_by

array.sort_by{|e| e.something}

or

Click to copy

sort_lambda = lambda{|e| e.something}
array.sort_by(&sort_lambda)

With latter you can reuse sort_lambda in other sort_by statements
