<script type="text/javascript">
	//replace a string
	var astring = "Peter picked a peck of pickled peppers, how many peppers did Peter Piper pick?";
	console.log(astring.replace(/peppers/gi,"parsnips"));
 
	//truncate a string
	console.log(astring.substr(0,30));
 
	//display numbers 0 -> 100 skipping 2
	for(var i = 0; i<=100; i+=2){
		if(i == 0)
			console.log(0);
		else
			console.log(i-1)
	}
</script>
