Backslash on strings

FirstLine
          \SecondLine
ThirdLine

My code:

const myStr = "FirstLine\n\tSecondLine\nThirdLine";

Error:
SecondLine should be preceded by the backslash character.

How do I include the backslash on the “SecondLine”?

The \ character is used as the escape character. In order to use it as a string literal, you need to escape the escape character.
