Split string with commas to new line

Question

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
         


        

Answer 1

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("
")

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'); .
