Jquery, it’s time to master, but how much?

If you are familiar with JavaScript then it doesn’t take long to grasp jquery. To understand how it works you just need to be playful with jquery. After mastering in jquery,I with my experience have categorized the different level of jquery and the time it will take for the following to achieve it. .
1.Basic :It will just take few hours
2.Understanding : It will take few days i.e (2-5) depends on you
3.Average: It will take some more days i.e(5-7) depending on your sincerity and interest .
4.Expertise: It will take a bit longer i.e (15-30 days)

Similarly if you aren’t familiar with JavaScript then it will take a bit longer to grasp jquery. To understand how it works you have to understand basic looping (i.e for) , conditional statements(i.e if -else) , constant , variables , sessions , storage etc.Again I have categorized the following rank based on the view that you know any one of the programming language:
1.Basic:It will just take few days (3-5)days
2.Understanding: It will take few days i.e (7-10) depends on you
3.Average: It will take some more days i.e(10-15) depending on your sincerity and interest
4.Expertise: it will take around a month

So you can categorize yourself with the below information:


1. Basic:(Beginner- level):

You should be good in looping, should know about sessions , local storage, cookies.

  • You should know about the load , ready method,
