JavaScript and forward slashes in strings

Question

What is the real reason that we must escape a forward slash in a JavaScript string, and also why must we escape string/no string in XHTML. A lot of tutorials just brush ove

Answer 1

You don't need to escape / in a JavaScript string, just \, because if you don't, then the string yes\no will inadvertently be transformed into yeso. Escaping the \ will prevent that.

Also, if you don't escape & in a URL, then whatever comes after it will be considered a new parameter. For example, a=Q&A will mean "the parameter a has the value "Q" and there's also a parameter A" instead of "the parameter a has the value "Q&A"". The correct way of escaping that would be a=Q%26A.
