Rails mapping array of hashes onto single hash

Question

I have an array of hashes like so:

 [{\"testPARAM1\"=>\"testVAL1\"}, {\"testPARAM2\"=>\"testVAL2\"}]

And I\'m trying to map this onto sin

Answer 1

Here you can use either inject or reduce from Enumerable class as both of them are aliases of each other so there is no performance benefit to either.

 sample = [{"testPARAM1"=>"testVAL1"}, {"testPARAM2"=>"testVAL2"}]

 result1 = sample.reduce(:merge)
 # {"testPARAM1"=>"testVAL1", "testPARAM2"=>"testVAL2"}

 result2 = sample.inject(:merge)
 # {"testPARAM1"=>"testVAL1", "testPARAM2"=>"testVAL2"}
