Answer 1

I think you want to do:

a = a.slice(1, -1);

Answer 2

a.substring(1,a.length-1)
1,2,3,4

Answer 3

What about:

'(1,2,3,4)'.replace(/[()]/g, '')

Which will remove all (s) of the characters in the string, giving you:

"1,2,3,4"

Answer 4

Another alternative:

var a='(1,2,3,4)';
a.replace(/^\((.*)\)$/, "$1");
