JS: function pushing value into parametred localStorage.address?

I try to create a if ... then... function to push objects into wished localStorage. However, the simple function to push objects into the wished localStorage fails. In localStorage.mydata the parameter mydata is considered as a variable.

JS such:

function pushToLocalStorage(mydata, num) {
   localStorage.mydata = num ;
}
pushToLocalStorage("data", 42);
pushToLocalStorage("data2.name", "Hello!");

But I indeed wish to push my values into localStorage.data and localStorage.data2.name.

How to make a function pushing input into a specified localStorage.specificName ?

You can do:

function pushToLocalStorage(mydata, num) {
    localStorage.setItem(mydata, num);
}

Retrieve with localStorage.getItem(mydata); <--- Replace mydata with key name.

Also, if you haven't already, be sure to check if the browser even supports localStorage.

Replace localStorage.mydata by localStorage[mydata] and it works: 

function pushToLocalStorage(mydata, num) {
    localStorage[mydata] = num ;
}
pushToLocalStorage("data", 42)
