By just creating a function you can achieve re-usability.

For example: 3 testers are automating an application. All 3 wanted to login. So instead of creating code by all 3 people only one person create login code in a function. That function can be used by other 2. This is also called Modular programming.


Or

In all the web applications common web objects will be there like

1.button--click

2.edit----enter characters

3.radio button---click

4.drop down----select

5.link-----click

etc........for all the objects make one generic functions add it in library files make use in all the actions this is called as re-useability.
