find minimum value in array javascript

So we are going to use javascript function Math.min(). Found insideThese methods are useful for avoiding extra loops and if statements to determine the maximum value out of a group of numbers. To find the maximum or the minimum value in an array, you can use the apply() method as follows: var values ... For example, see the below code.typeof __ez_fad_position!='undefined'&&__ez_fad_position('div-gpt-ad-delftstack_com-medrectangle-4-0'), The apply() function calls a function with a given this value and a given array in the above code. Problem Statement. Go to the editor Sample array : array1 = [1,0,2,3,4]; array2 = [3,5,6,7,8,13]; Expected Output : [4, 5, 8, 10, 12, 13] Click me to see the solution. The searched value. The MAX_VALUE property has a value of approximately 1.79E+308 or 21024. fill () overwrites the original array. Joined. And we have also used the ES5 method like Array.forEach() and Array.reduce() to get the same result. I hope you read the full article and I am very excited to get a comment on this post to get your review. First loop identifies the minimum value and the second loop all values which equate to the minimum value. The following code works and is done through 2 loops. We will repeat this procedure until we reached index 0. So let's move to our code section. map may be a function mapping the value to be checked or a string acting as a shortcut.
