How do I replace single quotes with double quotes in JavaScript?

Question

The following code replaces only one single quote:

var a = "[{'column1':'value0','column2':'value1','column3':'value2'}]";  var b = a.replace("'", "\"");  console.log(b);

Answer 1

var a = "[{'column1':'value0','column2':'value1','column3':'value2'}]";  var b = a.replace(/'/g, '"');  console.log(b);

Edit: Removed \ as there are useless here.
