How Can I Efficiently Find the Minimum and Maximum Values in a JavaScript Array?

Finding Minimum and Maximum Array Elements in JavaScript

Determining the minimum or maximum value in an array is a recurring task in programming. In JavaScript, there are native array methods like sort(), but they are not optimized for this purpose.

Augmenting the Array Prototype

Instead, a common approach is to augment the built-in Array object to leverage the native Math.max/Math.min functions:

Array.prototype.max = function() {
  return Math.max.apply(null, this);
};

Array.prototype.min = function() {
  return Math.min.apply(null, this);
};

This extended functionality provides the following functionality:

let array = [100, 0, 50];

console.log(`Max value is: ${array.max()}`); // Outputs: 100
console.log(`Min value is: ${array.min()}`); // Outputs: 0

This approach offers both simplicity and efficiency, as it utilizes existing JavaScript primitives to extend the standard array functionality.
