JavaScript: Find the lowest value in an array

JavaScript Math: Exercise-7 with Solution

Find Minimum in Array

Write a JavaScript function to find the lowest value in an array.

Test Data :
console.log(min([12,34,56,1]));
console.log(min([-12,-34,0,-56,-1]));
1
-56

Visual Presentation:

Sample Solution:

JavaScript Code:

 // Define a function named min that takes an input array.
function min(input) {
    // Check if the input is an array, if not, return false.
    if (toString.call(input) !== "[object Array]")
        return false;
    // Return the minimum value from the input array using Math.min.apply.
    return Math.min.apply(null, input);
}

// Output the minimum value from the array [12, 34, 56, 1] to the console.
console.log(min([12, 34, 56, 1]));
// Output the minimum value from the array [-12, -34, 0, -56, -1] to the console.
console.log(min([-12, -34, 0, -56, -1]));

Output:

1
-56
