title: How to increment a variable, like the line number, in a vscode snippet
body: <p>I have a multi-line snippet in VScode.  The problem is, TM_LINE_NUMBER gives the number of the line where the snippet was triggered, I need to increase that number by 1 so it equals the line number that it is actually on.</p>
  
  <pre><code>"Console_Log_Test": {
    "prefix": "clg",
    "body": [
      "//Debugging (remove)",
      "console.log('Line #${TM_LINE_NUMBER}');"
    ]
  },
  </code></pre>
  
  <p>How can I do that?</p>
