I am trying to push data in my local storage value, but it is giving me error this.dataObj.push is not a function

Unable to find where i am going wrong, sectionObj, dataObj both are arrays, please advise

file.ts

myname = '';
sectionObj = [];
getresume = {};
dataObj = [];
data = '';
save() {

    this.sectionObj = [{
        "name": this.myname,
        "contactno": "0",
        "email": "a@a.com"
    }];


    this.data = localStorage.getItem('resume'); //get existing item in localstorage
    if (this.data) //check if it exists or not empty
    {
        this.dataObj = JSON.parse(this.data); //parse string
        this.dataObj.push({
            "name": this.myname,
            "contactno": '2',
            "email": "a@a.com"
        });

    }

    localStorage.setItem("resume", JSON.stringify(this.dataObj));
}

What's the value of `this.data` after reading it from localStorage? – Eddi Sep 01 '17 at 06:42
`console.log(JSON.stringify(this.data));` ? – Sharikov Vladislav Sep 01 '17 at 06:44

when you do this.dataObj = JSON.parse(this.data); it probably returns something that is NOT an array, that's why you have this issue... – Julo0sS Sep 01 '17 at 06:47
i am getting this in console `"{\"name\":\"saurabh..\",\"contactno\":\"0\",\"email\":\"a@a.com\"}"` – user2828442 Sep 01 '17 at 06:55

Like what @Julo0sS said. The output is not an array it's an object. – Swoox Sep 01 '17 at 07:03
what should be done , please can you mention in code, how can this be corrected – user2828442 Sep 01 '17 at 07:04
try something like https://stackoverflow.com/questions/20881213/converting-json-object-into-javascript-array – Julo0sS Sep 01 '17 at 07:05
i changed the way it is saved, now is this ok - `"[{\"name\":\"\",\"contactno\":\"0\",\"email\":\"a@a.com\"}]"` – user2828442 Sep 01 '17 at 07:05
