Replace all line break in a string with <br /> tag in javascript

How can I read the line break from a value with JavaScript and replace it with a <br /> tag?

Example:

var a = "This is man.
     Man like dog."

I would like my result to look something like

var a = "This is man.<br />Man like dog.";

Answer 1

var newString=oldString.replace(/\n/g,"<br />");

Answer 2

To be complete: I've encountered cases where '\n' didn't work, in those cases I used:

someString.replace(/\n/g,'<br />')
          .replace(/\r/g,'<br />')
          .replace(/\r\n/g,'<br />');
