Unescape an escaped string in JavaScript

Question

I'm running a loop to display characters of a specific Unicode escape sequence.

var es = '';

for (var i = 0; i <= 9999; i++) {
  if (i < 10) {
    es = '\\u000' + i;
  } else if (i < 100) {
    es = '\\u00' + i;
  } else {
    es = '\\u' + i;
  }
  console.log(es);
}

...however, it doesn't display the characters, just the sequence. Is there anyway in JavaScript to unescape the escaped sequence to force it show the character?

Answer 1

For anyone stumbling across this question (most likely my future self) looking to "unescape" a previously escaped Javascript special characters, here's a hacky way to do it:

newString = JSON.stringify(string).slice(1,-1)

However this seems to only work for certain characters, like \t, \n, \r, \f, \b, \\, etc.

To explain myself better, in the case of tabs, this will convert a tab character back into literal/raw string that is \t.
