Pull data from array into new array

Question

I have the following code. Legislators is an array of data.

testArray = Legislators.each { |legislator| legislator['name']['first']}

In powershell this would leave me with an array of the legislator's first names.

Do I need to add each legislator object to the testArray as I loop through? I feel like there's probably a shortcut...

Try

testArray = Legislators.map { |legislator| legislator['name']['first'] }

each only iterates over legislators and executes the block; map iterates over it and returns an array whose elements are the values of the block.
