How to use \n in a javascript string

Question

Example:

var i = 'Hello \n World'
console.log(i)

Would return:

Hello
World

and I want it to return

Hello \n World

not rendering the new line, as I intend to store this in a database.

You don't need to escape, as your Document Database will do JSON.stringify, I use ArangoDB and it works perfectly fine, thanks to @PaulPro

Answer 1

You would escape the \ with \\, which would tell the interpreter just to produce the character without processing it as a special character:

var i = 'Hello \\n World';
console.log(i)

Here are all the string escape codes:

• \0 The NUL character (\u0000)
• \b Backspace (\u0008)
• \t Horizontal tab (\u0009)
• \n Newline (\u000A)
• \v Vertical tab (\u000B)
• \f Form feed (\u000C)
• \r Carriage return (\u000D)
• \" Double quote (\u0022)
• \' Apostrophe or single quote (\u0027)
• \\ Backslash (\u005C)
• \x XX The Latin-1 character specified by the two hexadecimal digits XX
• \u XXXX The Unicode character specified by the four hexadecimal digits XXXX

Answer 2

Escape \n with \\n and store the string in DB. However, only \n can also be stored in DB.
