Hi there codeispoetry,
does this help…
wordsArray.length = 3
count ++
% is the modulus operator
count = 0, count%3 = 0
count = 1, count%3 = 1
count = 2, count%3 = 2
count = 3, count%3 = 0
count = 4, count%3 = 1
count = 5, count%3 = 2
count = 6, count%3 = 0
etc, etc

Yes sir, Thanks.
So it is the remainder that is finally counted. Right?
If yes then please help me further how the whole causation is working:
$(this).text(wordsArray[count % wordsArray.length]).fadeIn(400);
I think I got it. Repetition here:
0
1
2
0
1
2
0
1
2
Repetition giving array position in an infinite scheme.
Thanks. Very concise and crisp explanation. Thank you so much.
No problem, you’re very welcome.

Sir, can we also accomplish it through vanilla JS?
Yes, you may.
Here is an example…

You will notice that the CSS is removed from the script.

In JQuery(Javascript) array is not defined from “0”?
But 1,2,3,4,5… onwards?
Precisely,
In
wordsArray = ["Beta", "Gamma", "Delta", "Alpha"];
wordsArray[0]
is Beta or wordsArray[1]
is Beta?
What causes you to think that it starts at 1?
In JavaScript as with most other languages, it starts at zero.
I got it now. My previous understanding was a slight deviation →
It is actually:
1
2
3
0
1
2
3
0
So wordArrays[0]
also comes in the infinite loop.
