Now we will talk about that functions.
OK, now this is a simple example, as you can see, which is the Halo function.
As you can see, it defined your function here.
So hello.
And open the brackets, open the process and echo the word now to invoke your function.
You can just call its name, which is hello, like this and it will print Hello World.
Now let's see what will happen now.
So again.
Yeah, hello.
It worked 100 percent, but actually this is a simple lecture and a quick lecture.
But we talked about how the function work, OK, and it is exactly the same as the basic of programming.
OK, when you invoke the hallow function without putting the brackets destiny.
All right.
Thanks for watching.
