How to find the maximum value of an array in Javascript?

To find the maximum value of an array in JavaScript, you can use the Math.max() function in combination with the apply() method.

The Math.max() function returns the maximum of zero or more numbers. It can be called with multiple arguments, like this:

Math.max(x, y, z, ...);

However, if you have an array of numbers and you want to find the maximum value in the array, you can use the apply() method to pass the array as arguments to the Math.max() function.

Here is an example of how to use the Math.max() function with the apply() method to find the maximum value of an array:

const numbers = [1, 2, 3, 4, 5];
const max = Math.max.apply(null, numbers);

console.log(max); // 5

The apply() method takes two arguments: the this value and an array-like object or iterable containing the arguments to pass to the function. In this case, we pass null as the this value, since we do not need to use it in the Math.max() function.

You can also use the spread operator (...) to pass the elements of the array as arguments to the Math.max() function. This syntax is shorter and more readable, but is not supported in older browsers.

Here is an example using the spread operator:

const numbers = [1, 2, 3, 4, 5];
const max = Math.max(...numbers);

console.log(max); // 5
