I have a string "[[[[[]]]]]" and I want to convert it in "{{{{{}}}}}". I tried "[[[[[]]]]]".replace(/[/g,'{').replace(/]/g,'}') but not luck so far.

• 8 The [ is a special char in a regex, it must be escaped. – Wiktor Stribiżew Commented Feb 14, 2017 at 14:13

The [ square bracket has to be escaped.

var string = "[[[[[]]]]]";

console.log(string.replace(/\[/g, '{').replace(/]/g, '}'));

Try this:

var string = '[[[[]]]]';
console.log(string.replace(/\[/g, "{").replace(/\]/g, "}"));
