How to pass a for loop to the forEach method without changing anything (or almost nothing) in the code except for the for loop itself?

I have an image slider with buttons below the images:
How can I replace the for loop with the forEach method in this slider without changing anything in other parts of the code (or changing at a minimum)? I found a slider with the forEach method on the Internet, but there are some remainders from division and in general the code is written too intricately for me personally...

Wrong line break at least

url = f"https://query.yahooapis.com/v1/public/yql?q="\
              + f"select%20*%20from%20weather.forecast%20where%20w" \
              + f"oeid%20in%20(select%20woeid%20from%20geo.places("\
              + f"1)%20where%20text%3D%22{city}%22)%20and%20u%3D%2" \
              + f"7c%27&format=json&env=store%3A%2F%2Fdatatables.o" \
              + f"rg%2Falltableswithkeys"

And why did you create so many lines? You literally created 6 strings and concatenated them. If you really want to take advantage of the new feature, then use a multi-line comment url = f"""String {city} """

It is not necessary to explicitly specify string concatenation at all. you can do this:
url = " https://query.yahooapis.com/v1/public/yql?q= "\
"select%20*%20from%20weather.forecast%20where%20w" \
"oeid%20in%20 (select%20woeid%20from%20geo.places("\
f"1)%20where%20text%3D%22{city}%22)%20and%20u%3D%2" \
"7c%27&format=json&env=store% 3A%2F%2Fdatatables.o" \

images.forEach((img, i) => {
  img.style.display = (i === index - 1) ? 'block' : 'none'
