Replace double quotes in a string

[Christopher Benson-Manica]

Why doesn't this replace all double quotes in a string with the letter
Q?

source.replace( /"([^"]*)"/g, "Q$1Q" );

source.replace( /"([^"]*)"/g, "Q$1Q" );

It does for me. Are you forgetting to reassign the result to 'source'?

*sheepish* Yes

Because your regex looks for strings with at least two quotes, possibly
separated by other characters.
To replace all double quotes, no matter what, the regex is at its simplest:

source.replace( /"/g, 'Q' );
