Anescape character is acharacter that causes one or more characters that follow it to be interpreted differently. This forms anescape sequence, which is often used to represent a character that has an alternative meaning when printed literally, such as the quote character in a string literal. Escape sequences can have other usages too, especially inregular expressions.

• In JavaScriptregexes,string literals, andidentifiers, we can use the backslash (\) to escape characters like\',\",\u0026, etc.
• In CSS identifiers, we can use the backslash (\) to escape characters like\\,\n,\26, etc. Seeescape characters for more information.
• In HTML text content and attribute values, we can usecharacter references like<,<, or<.
