A unicode to character converter with text input and javascript

Question

I'm making a tool that converts unicode value to character with text input and javascript.

Here's what I've done so far, I am quite new to Javascript so I suppose the code looks quite odd:

setInterval(
function tochar() {
  const hex = +document.getElementById('hex').value;
  const char = hex.toString();
  document.getElementById("char").value = char;
});

unicode <input type="text" id="hex" value="\uac00"/>
➜char <input type="text" id="char"/>

I want to make the right input to render '가', which is the character value for \uac00. What edits should I make? I have already refered to a lot of questions and answers on StackOverflow and other sources, but could not find something helpful for my purpose.

This: `const char = hex.toString();` just sets `char` to exactly the same string that `hex` already is; "hex" is a String already, `toString()` on a String just returns the same string. It seems you're expecting that line to do some kind of conversion (?) — Stephen P, Jan 06 '21 at 17:20
@epascarello I've seen this one, but it looks like the answers mainly deal with hexadecimals. I'm not sure how to make use of this. — Henry, Jan 06 '21 at 17:20

function tochar() {

  // Get input
  let hex = document.getElementById('hex').value;
  
  // Remove \u
  hex = hex.slice(2);
  
  // Convert to char
  const char = String.fromCharCode(parseInt(hex,16));
  
  // Show
  document.getElementById("char").value = char;
};
tochar();

unicode <input type="text" id="hex" value="\uac00"/>
➜char <input type="text" id="char"/>
