How exactly works

- \r carriage return
- \b backspace
- \f form feed

I just tested them in browser’s console.  
The last two give  
var a = “test\ba”;  
var b = “test\fb”;  
console.log(a); // testa  
console.log(b); // testb

I don’t know why both generates an “strange” character.  
\r does nothing  
var c = “test\rc”; // testc
