For coding, each yard may have its own set of styles, many people may not care about the coding style at all, because the final compiler compiled by the target code will not be affected. But in the development of a large project, the most

Why JavaScript is generated:In the age of dial-up, the form data must be sent to the server to verify that the input is valid, and JavaScript is developed to solve this problem so that the client can verify the validity of the input
