You could just replace the last zero, if exist.

const
    format = number => number.toFixed(3).replace(/0$/, '');

console.log([65.110, 65.111, 65.100, 65.000].map(format));

getting error like map is not function – Vijay Pathipaka Feb 18 '22 at 10:10
you need only the function `format`, maybe without arrows, like `function format(number) { return number.toFixed(3).replace(/0$/, ''); }`. – Nina Scholz Feb 18 '22 at 10:21
