regex - How can I replace newlines/line breaks with spaces in javascript?

Question

I have a var that contains a big list of words (millions) in this format:

var words =  "
car
house
home
computer
go 
went
";

I want to make a function that will replace the newline between each word with space.

So the results would something look like this:

car house home computer go went

You can use the .replace() function:

words = words.replace(/
/g, " ");

Note that you need the g flag on the regular expression to get replace to replace all the newlines with a space rather than just the first one.
