Find the largest and smallest numbers in an array in JavaScript using Math.max() and Math.min().

const numbers = [2, 8, 82, 51, 6];
const largestNumber = Math.max(...numbers);
const smallestNumber = Math.min(...numbers);

console.log('largestNumber is', largestNumber);
console.log('smallestNumber is', smallestNumber);

Output:

largestNumber is 82
smallestNumber is 2

• Here, spread operator converts an array into individual arguments.
• So Math.max and Math.min expect a list of arguments, not an array directly.
• For small and medium size arrays Math.max and Math.min are the simplest and most effective way.
• For Large Arrays we need to use Array.reduce() for better performance.
• And most importantly Math.max and Math.min works only for array of numbers.
