When you split("d") in the program, are we not suppose to have 4? Why 3?

Question

var arr = "donald".split("d")
document.write(arr.length)

Answer 1

"donald".split("d")
= "|d|onal|d|"
= "", "onal", ""

Answer 2

Hmm Dhanush Adithya, thanks

Answer 3

Thank you guys for answers Dhanush Adithya and ODLNT but still, you guys haven't explained why the output of the code is 3

Answer 4

If you cut the string "donald" from 2 points:
"" 🔪 "onal" 🔪 ""
The length is 3, because also empty strings will be separated.
I somehow understand how you got 4, but I can not explain it. I can only say, that if you cut a string 2 times, result will be 3 strings.

Answer 5

Answer 9

Mofey,
Add this to your snippet - document.write("<br/>"+JSON.stringify(arr));
It will answer your question.

Answer 10

Mofey
Like Seb TheS said if you split the it'll be separated and it'll store the separate stings in an object
When you use the .length it'll display the object's length as 3
After using join() the empty strings is joined to the original string
So it again becomes a string after using join() and the output will be 4
By the way , it's an nice question
