Remove hyphenate throughout the file

This jsx script turns off hyphenation in an active document, also modifies Paragraph styles accordingly. The code isn't mine, sorry, couldn't detect original author now...

Application.prototype.main=function()
{
if(this.documents.length>0)
{
var doc= this.activeDocument;
doc.stories.everyItem().hyphenation=false;
var paraSt = doc.paragraphStyles.everyItem().getElements();
for(var i=0; i<paraSt.length; i++)
{
if(paraSt.name.indexOf("[")==-1)
{
paraSt.hyphenation=false;
}
}
}
}
app.main();
alert("Hyphens removed!");
