Using VAriable in replace() using javascript

Can I use variable in replace function for old and new string? I know that old new string can be variable. How abt old string? Replace all "The" to "Ze" using variable not literals.

Thanks

var str = "The Lord of the Rings: The Fellowship of the Ring"; 
 
var news = "ze";
 var old = "The"
var result = str.replace(/old/gi,news);
 
document.write(result);
</script>

I think str.replace(old,news); also does the job,
