handle empty localstorage

[UmangThapliyal]

Currently we will initialize the var as empty string and we are checking the length of itinstead we should check the value. There are two condition currently where when we are running in browser we are taking it as string because localstorage and when in node we are taking as array because there we have variable we need to make sure we are using one data type

after addong the condition not getting other logs checking this

[UmangThapliyal]

the issue was because of the js closure where the function will have different scope we have to bind this to the function and then call it
