How to use each in rails to display values of an array

Question

I have a @keyword variable which holds the string "cat dog mouse bird"

I want to display the values of each word under a span element.

My algorithm looks like

<%= @keyword.split.each {|key| "<span>#{key}</span>".html_safe %>

but when viewing it, it displays an array of [cat dog mouse bird]

Answer 1

<%= @keyword.split.map {|key| "<span>#{key}</span>".html_safe }.join("\n") %>
