Javascript Replace with Global not working on Caret Symbol

Question

i have following code for replacing

 var temp =  \"^hall^,^restaurant^\";
 temp.replace(/^/g, \'\');
 console.log(temp);

This does not Replace

Answer 1

 temp = temp.replace(/\^/g, '');

It is replacing once you escape the caret.

And note that just writing temp.replace(/\^/g, ''); doesn't update your actual string. That is the reason you have to write

 temp = temp.replace(/\^/g, '');
