Can i write a program in JavaScript to count the number of vowels using string.includes() and for of loop? [closed]

I have tried passing strings to the getCount function that contain ‘aeiou’ and not but the value vowelsCount is always 0.

I tried using string includes() function using the documentation provided by the very kind and helpful mdnwebdocs, but it always returns count as 0, I have the code with which we can get the exact number of vowels in a string, but I prefer to use the approach taught by mdnwebdocs.
