Using SetAttribute we can achieve this.
Example

function loadFile_Js_CSS(filename, filetype) {
  if (filetype == "js") { //if filename is a external JavaScript file
    var fileref = document.createElement('script')
    fileref.setAttribute("type", "text/javascript")
    fileref.setAttribute("src", filename)
  } else if (filetype == "css") { //if filename is an external CSS file
    var fileref = document.createElement("link")
    fileref.setAttribute("rel", "stylesheet")
    fileref.setAttribute("type", "text/css")
    fileref.setAttribute("href", filename)
  }
  if (typeof fileref != "undefined")
    document.getElementsByTagName("head")[0].appendChild(fileref)
}
