title: best way to remove strings in array with Ruby
body: <p>lets say i've got this array:</p>
  
  <pre><code>array = ["str1", "str2", "str3", "str4", "str5", "str6", "str7", "str8"]
  </code></pre>
  
  <p>what i'm doing:</p>
  
  <pre><code>array.delete_if {|i| i == "str1" || i == "str3" || i == "str5"}
  </code></pre>
  
  <p>i got:</p>
  
  <pre><code>["str2", "str4", "str6", "str7", "str8"]
  </code></pre>
  
  <p>are there any better approach in ruby to do this ?</p>
