Logical nullish assignment (??=) gives an error in Visual Studio Code

by

Logical nullish assignment is giving SyntaxError: Unexpected token '??=' in the Visual Studio Code. Is there any solution for this error?

I am trying this code;

const a = { duration: 50 };

a.duration ??= 10;
console.log(a.duration);
// expected output: 50

a.speed ??= 25;
console.log(a.speed);
// expected output: 25

  1. Try adding this or similar to your eslintrc.json file (or wherever you have your eslint options):

    {
  ... other options

  "parserOptions": {
    "ecmaVersion": 2020,   <== you need this or a similar more recent option
    "sourceType": "module"
  },
  ... other options
}
