When the above code is executed, the following output is generated.
Before un-shifting ------------- Jag Chat Win Dhan
After un-shifting ------------- aaa Jag Chat Win Dhan
The above code is very similar to the code available in the previous section with only the following change:
Earlier, in my first section, I used the “push” method. When we apply “push” with a parameter, the parameter (or element) gets added to the array at the end (or gets appended). The new method “unshift” is very similar to the method “push” except that it adds at the end. Apart from this difference, the rest of the code is quite similar.
By now, I hope you are very clear about all the ways of working with arrays. I used very simple examples, so that the clarity of the subject would be maintained with simplicity. You can practice further by developing extended simple applications.
You can have a few textboxes and lists on a web page and continuously add/delete/clear elements in an array dynamically with a few buttons, using all of the methods I described in this series. I bet that it would really get you started with mastering arrays.
