I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>
) will also add backticks around text.
2 posts were split to a new topic: I do not see how knowing how to do something like this will help a person build a website
For one thing, to the best of my knowledge JS does not allow complex evaluations like this:
if (77 >= arr2[i] >= 65) {
You would need to break it into parts and use an and
logical operator, like this:
if (arr2[i]<=77 && arr2[i]>=65) {
Thank you very much. I didn’t know that!
