js-SessionStorage

# sessionStorage
store a value `sessionStorage["key"] = "value";`


## Store multiple values
- to store values "one", "two", "three"
	store as follows : `sessionStorage['key"] = ["one", "two", "three"];`

- to retrieve multiple values stored use as follows
	`var array = sessionStorage["key"].toString().split(",");`

## Integer values
Integer values are not directly accessible without any conversion. So they should be converted as follows
- var id = Number(String(sessionStorage["key"]));

## Check if key exists/ data is already availble (only case when tab is reloaded)
`if (sessionStorage["idd"]) console.log("exists");`
