@mui/material/Select/utils/areEqualValues.mjs

Material UI is an open-source React component library that implements Google's Material Design. It's comprehensive and can be used in production out of the box.

export default function areEqualValues(a, b) {
  if (typeof b === 'object' && b !== null) {
    return a === b;
  }

  // The value could be a number, the DOM will stringify it anyway.
  return String(a) === String(b);
}
