title: How do I split string using `if` condition and separator
body: <p>I have a variable in javascript with text separated with commas, for example:</p>
  
  <p><code>var array = "hello,goodbye,test1,test2,1,90m tall";</code> [NO SPACE AFTER COMMAS]</p>
  
  <p>If I use <code>.split(',');</code> the result is as follows:</p>
  
  <pre><code>array[0] = hello
  array[1] = goodbye
  array[2] = test1 
  array[3] = test2
  array[4] = 1
  array[5] = 90m tall
  </code></pre>
  
  <p>But I want this:</p>
  
  <pre><code>array[0] = hello
  array[1] = goodbye
  array[2] = test1 
  array[3] = test2
  array[4] = 1,90m tall
  </code></pre>
  
  <p>How can I do it? I can imagine I have to add some special restriction but I don't know how...I also checked regex but...no success.</p>
