I got this out put from asyncstorage multiget. why it get backslashes with its output?

Array [
  "defaultData",
  "\"{\\\"fullName\\\":\\\"asas\\\",\\\"livingCountry\\\":\\\"1\\\",\\\"monthlyIncome\\\":\\\"0\\\",\\\"height\\\":\\\"4\\\",\\\"weight\\\":\\\"12\\\"}\"",
]

I tried to convert it into object but it also getting that backslashes with its property.

Object {
  "obj": "{\"fullName\":\"asas\",\"livingCountry\":\"1\",\"monthlyIncome\":\"0\",\"height\":\"4\",\"weight\":\"12\"}",
}
