replace all double quotes in a string javascript

I decided to post this. I always forget syntax for replacing double quotes in javascript.
There are tons of posts for replacing doubles quotes but still tough to find when i need urgently.

//code sample
// this is string with lots of double quotes 
var err = "blahahahah a string with lots of double quotes ";
alert (err);  //  this will alert string with double quotes.

err = err.replace(/\"/g, "");                      
alert (err);  //  this will alert string without  double quotes.



This is a simple regex for replacing all double quotes in javascript.  "/g" is for replacing all double quotes in a string.
