JavaScript uses the    backslash  as an escape characters for       single quote    double quote   backslash  n new line  r carriage return  t tab  b backspace  f form feed  v vertical tab  IE  lt  9 treats   v  as  v  instead of a vertical tab    x0B    If cross-browser compatibility is a concern  use  x0B instead of  v    0 null character  U 0000 NULL   only if the next character is not a decimal digit  else it   s an octal escape sequence    Note that the  v and  0 escapes are not allowed in JSON strings

If your goal is to have  str    Hello nWorld     and output what it contains in string literal form  you can use JSON stringify   console log JSON stringify str         Hello nWorld      x000D   x000D  const str    Hello nWorld   x000D  const json   JSON stringify str   x000D  console log json        Hello nWorld   x000D  for  let i   0  i  lt  json length    i    x000D      console log    i     json charAt i      x000D    x000D   as-console-wrapper   x000D      max-height  100   important  x000D    x000D   x000D   x000D    console log adds the outer quotes  at least in Chrome s implementation   but the content within them is a string literal  yes  that s somewhat confusing    JSON stringify takes what you give it  in this case  a string  and returns a string containing valid JSON for that value  So for the above  it returns an opening quote      the word Hello  a backslash      the letter n  the word World  and the closing quote      The linefeed in the string is escaped in the output as a   and an n because that s how you encode a linefeed in JSON  Other escape sequences are similarly encoded
