title: Lua Removing first couple characters without add a space
body: <p>I'm new to Lua and I'm sure this is a silly problem.</p>
  
  <p>I was trying to remove first 3 characters from a string with string.gsub
  Here is the code:</p>
  
  <pre><code>string.gsub(m, "/jk", "", 1)
  </code></pre>
  
  <p>Now "/jk" are the first 3 chars the string, now, string.gsub adds a space instead of removing them. My question is, how to remove them without adding the space?</p>
