URL에서 &amp ;사용하는 이유

1. 사용이유

HTML uses characters like ampersand, greater than, less than, etc. in its syntax. So if someone wants to use those symbols in their web page, when they're putting the text in the HTML they need to put "&amp" for an ampersand, "&gt" for greater than, etc. When the browser displays the webpage, it understands to replace those with the proper characters.
