For Loop is a very basic JavaScript knowledge, but because Javascript is too flexible, there may be some writing that causes beginners to crash. I decided to explain the For Loop in a simple way. It would be helpful for new users who are still new

1. character location search function: Strpos ($ STR, search, [int]): searches for the first position of search in $ STR starting from int; Stripos ($ STR, search, [int]): the position where the string first appears in another string. This function

I. Basic for loop writingThe Code is as follows: Copy codeThe Code is as follows: // Example 1 for (var I = 1; I Alert (I ); } This code is too simple and I am so embarrassed to come up with it. The execution result of the Code is 1 to 10 in
