library and NPM module that extends Handlebars with Helpers for Code Generation in a specific programming language (e.g. Javascript)

<script language="javascript">

  function el(pID) {
    return document.getElementById(pID)
  }

  function convert(pTplID)
  {
    var vTplID = pTplID || "javascript";
    var vJSON;
  	var vString = document.fconvert.jsonstring.value;
    if(vString) {
      try {
          vJSON = JSON.parse(vString);
      } catch(e) {
          alert("JSON Parsing Error: "+e); // error in the above string (in this case, yes)!
      };
      if (vJSON)  {
        setTemplate(pTplID);
        document.fconvert.output.value = Handlebars4Code.compile_code(vTplID,vJSON);

      } else {
        alert("ERROR: Could not parse JSON")
      }
    }
  }

  function setTemplate(pTplID) {
    //convert(pTpl);
    el("tTemplate").value = vDataJSON.tpl[pTplID];
  }
