#100DAYSOFCODE D28 - Basic JavaScript: Escape Sequences in Strings

Quotes are not the only characters that can be escaped inside a string. There are two reasons to use escaping characters: First is to allow you to use characters you might not otherwise be able to type out, such as a backspace. Second is to allow you to represent multiple quotes in a string without JavaScript misinterpreting what you mean. We learned this in the previous challenge.
CodeOutput
\'single quote
\"double quote
\\backslash
\nnewline
\rcarriage return
\ttab
\bbackspace
\fform feed
Note that the backslash itself must be escaped in order to display as a backslash.


Assign the following three lines of text into the single variable myStrusing escape sequences.
FirstLine
    \SecondLine
ThirdLine
You will need to use escape sequences to insert special characters correctly. You will also need to follow the spacing as it looks above, with no spaces between escape sequences or words.
Here is the text with the escape sequences written out.
