Today I want to show you how to get the index of the max value in an array using JavaScript. When we work with an array of numbers, sometimes we need to find out what’s the maximum value, and then find its pos
Using indexOf() with Math.max() Method To get an index of the max value in a JavaScript array: Use the Math.max() function to find the maximum number from the given numbers. Here, we passed an array and used the spread operator (...) to expand the array into individual elements. ...
Output: 2 In the example above, we have used theMath.max(..arr)to get the max value of an array, then we have passed the max value to the Array.indexOf() method to get index of it. TheMath.max()method accepts only the individual values but not an array, so we unpacked the arr...
You can use the Math.max() and Math.min() methods in combination with the apply() method to find the maximum or minimum values within an array or an array-like object, like this:ExampleTry this code » var numbers = [1, 5, 2, -7, 13, 4]; var maxValue = Math.max.apply...

您也可以使用 Array.foreach() 函数: varfruits, text; fruits= ["Banana", "Orange", "Apple", "Mango"]; text= " "; fruits.forEach(myFunction); text+= " ";functionmyFunction(value) { text+= " " + value + " "; } 3、数组和对象的区别 ...
