How to get first instance to last instance of a number in a string in javascript regex/ object error? -

i have string "{\"id\":\"35112914\"}" obtained after json.stringify . want number 35112914 or first instance of number ,i.e. 3 last ,i.e., 4 . there other way of approaching ?

edit: had stringify because of weird error getting. while accessing property of object, getting undefined answer , made number inaccessible. stringify atleast shows number .

edit 2 :

my code written in node makes curl request rest api .

curl.request(optionsrun, function (error, response) {                 console.log(response);                 settimeout(function () {                     id = response ;                     console.log(id["id"]) ;                 },2000) ;             }) ; 

output:

{"id":"35113281"} undefined 

you need parse response js object before can access using js object methods:

curl.request(optionsrun, function (error, response) {   var id = json.parse(response);   settimeout(function () {     console.log(id.id) ;   }, 2000); });
