JavaScript Escape

In JavaScript, if a string contains the same quote used to wrap it (like a single quote inside a single-quoted string), it will cause a syntax error unless escaped.

The backslash (\\) is the escape character. It indicates that the character following it should be treated specially, such as \\n for a new line.

While escaping helps in valid syntax, it is only one part of security. Always use proper sanitization libraries when rendering user-generated content in HTML.
