Fast way to get the min/max values among properties of object

let obj = { a: 4, b: 0.5 , c: 0.35, d: 5 };

let arr = Object.values(obj);
let min = Math.min(...arr);
let max = Math.max(...arr);

console.log( `Min value: ${min}, max value: ${max}` );

let obj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var arr = Object.keys( obj ).map(function ( key ) { return obj[key]; });
