Display accent character ignoring the extra backward slash

I have a string with accent character with an extra backward slash.

const name = "V\\u00E1ci"
console.log(name); // prints  "V\u00E1ci"

I am finding it hard to display it properly, tried various combination of string replace, searched web. but no luck :(

Is there any way I can convert above name to display properly ignoring the first extra backward slash?

This is how, it should be displayed.

You can run the string through the JSON Parser, using JSON.parse().

Working Example:

const processString = (myString) => {

  myString = JSON.parse('"' + myString + '"');
  
  return myString;
}

console.log(processString('V\\u00E1ci'));

Why does this work?

Simply because when you convert a Javascript string into a JSON string, the JSON Parser will automatically convert any code point escape sequences into the corresponding Unicode characters.

It's not extra backwards slash in the string. the first \ is a escape character, so that you can add othervice not allowed characters in a string:

const s = "\"\""  // """"

What you need to do is to replace string '\u00E1' with the characer á. Like this

const name2 = name.replace("\\u00E1", "\u00E1"); // Váci

You can use the npm package https://www.npmjs.com/package/unescape-js to do this.
