To help format text programmatically, JavaScript exposes several default JavaScript String methods and a single property for which the JavaScript String object commands, and all of which any text-containing JavaScript variable can directly access. The below example shoes how to set-up text string using JavaScript.

Example of String Methods in JavaScript

<script language="javascript">
  var myString="Welcome at Global Guide Line! JavaScript Tutorial"
  var format=myString.toUpperCase()
  var size=1
  //go through the myString, letter by letter with JavaScript for loop
  for (i=0;i<myString.length;i++){
    document.write(format.charAt(i).fontsize(size).bold())
    if (size<7){
      size++
    }
    else{
      size=1
    }
  }
</script>

Result for above Example of JavaScript with String Object.
