I have a string like

This is great day, tomorrow is a better day, the day after is a better day, the day after the day after that is the greatest day

I wanted to basically split this one long string at the commas and insert a new line so it becomes

This is great day

tomorrow is a better day

the day after is a better day

the day after the day after that is the greatest day

How can I do that ?

With the built in split and join methods

var formattedString = yourString.split(,).join(n)

If you'd like the newlines to be HTML line breaks that would be

var formattedString = yourString.split(,).join(<br />)

This makes the most sense to me since you're splitting it into lines and then joining them with the newline character.

Although I think speed is less important than readability in most cases, I was curious about it in this case so I've written a quick a benchmark.

It seems that (in chrome) using str.split(,).join(n) is faster than str.replace(/,/g, 'n'); .
