Examples of common escape characters are \' (Single Quote) and \" (Double Quote). Example: let str = "This is a \\"test\\" string"; console.log(str); // Output: 'This is a \"test\" string'No, slash (/) is not considered a special character in JavaScript. It is a regular non-alphanumeric character.You can use the `strip()` or `replace()` functions to remove backslashes from a string. Example: ```python my_string = "My\\string\\has\\backslashes" # Using strip() no_backslashes = my_string.strip('\\') # Using replace() no_backslashes = my_string.replace('\\', '') print(no_backslashes) # Output: Mystringhasbackslashes ```
