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;

Q:

How do you decide when to use HashMap and when to use TreeMap ?

Answer

For inserting, deleting, and locating elements in a Map, the HashMap offers the best alternative. If, however, you need to traverse the keys in a sorted order, then TreeMap is your better alternative. Depending upon the size of your collection, it may be faster to add elements to a HashMap, then convert the map to a TreeMap for sorted key traversal.

Q:

What is Javascript namespacing? How and where is it used?

Answer

Using global variables in Javascript is evil and a bad practice. That being said, namespacing is used to bundle up all your functionality using a unique name. In JavaScript, a namespace is really just an object that you’ve attached all further methods, properties and objects. It promotes modularity and code reuse in the application.
