String.replace(Regex) returns undefineds

Question

My example is paired down but I believe it communicates my problem:

I have a simple string var data = '360–400 ' for sake of example:

data.replace('&nbsp;');

returns:

//360–400undefined

Question: how do I make sure my output doesnt leave undefines in the string

You need to pass a second parameter to the .replace() method in order to replace the matched value. If you simply want to remove the value, just pass an empty sting, '':

data.replace('&nbsp;', '');

The reason it was replacing the value with undefined was simply because the second parameter was undefined.
