To get the highest or lowest number from an array in JavaScript, you can use the Math.max() or the Math.min() methods then spread the elements from the array to these methods using the spread operator (...).

Consider this array of numbers,

// number array
const numberArr = [23, 122, 1, 23, 4, 56];

Now let's use the Math.max() and Math.min() methods and use the spread operator on the array like this,

// number array
const numberArr = [23, 122, 1, 23, 4, 56];

// get highest number
const highest = Math.max(...numberArr);

// get lowest number
const lowest = Math.min(...numberArr);

console.log("Highest Number: " + highest); // Highest Number: 122

console.log("Lowest Number: " + lowest); // Lowest Number: 1

• Both the methods Math.max() and Math.min() returns a number.

See the above example live in JSBin.
