Q:

Are you comfortable offering our charge account to customers?

Answer

A candidate should not be shy here. Someone who tells you that they are uncomfortable when being solicited for proprietary charges by other retailers will not be successful in your organization. If that is something that you as a candidate struggle with, make sure that you portray your desire to succeed. Tell the employer that it is something that you are gaining skills on, and would love the opportunity to perfect your script.

Q:

What is session storage and how can you create one?

Answer

Session storage is same like local storage but the data is valid for a session. In simple words the data is deleted as soon as you close the browser.


To create a session storage you need to use “sessionStorage.variablename” . In the below code we have a created a variable called as “clickcount”.


If you refresh the browser the count increases. But if you close the browser and start again the “clickcount” variable starts from zero.


if(sessionStorage.clickcount)


{


sessionStorage.clickcount=Number(sessionStorage.clickcount)+1;


}


else


{


sessionStorage.clickcount = 0;
