Why doesn’t split(“ “) work, while split(/\s+/) does?

Question

Hello, I was solving a JavaScript coding problem on freeCodeCamp and submitted my solution (code attached in this post). Unluckily my solution hasn’t been accepted even though the output in the console is the expected one. 

The solution of FCC is the same as my code, but instead of split(“ ”), they used split(/\s+/), using a regex in parenthesis.
My question is: in this case technically split(“ “) should be correct, right? If not, could you kindly explain to me why?

Thanks in advance.

There might be more spaces between 2 words like:

abc xyz

so in this case split(" ") may not work because you have given a single space in split function.

Just try to give more space in your code String and see effect.
