the difference between Jquery remove() and empty()

if you don't know the difference between Jquery remove() and empty() function , i will tell you.
for example:

1. <p>Hello</p>
2. World
3. <p>welcome</p> 

$('p').empty(); 
output:
<p></p>
World
<p></p> 

Execution of $("P").Empty () is the result of :
output:
World

Summary:
Jquery empty() function is clear element text, but remove() function will delete all, include element itself.
