Javascript In this problem, we are given an array of integers, which may contain both negative and positive numbers. We have to find the average of all the negative numbers in the array. In this article, we are going to learn how we can find the average of all negative numbers in an ...
There is no built-in method to get an average in JavaScript. We usually do different tricks and ways to achieve that functionality to count an average of defined values.
一、find()方法: 功能:返回第一个满足条件的元素,无符合项时返回undefined。 const numbers = [10, 20, 30, 40]; const result = numbers.find((num) => num > 25); console.log(result); //结果:30,因为30是数组numbers中第一个大于25的元素。 1. 2. 3. 4. 参数: callback(element, index, ...
Approach 3: Using an Array to Find the Average You can also calculate the average of three numbers by storing them in an array and then performing the summation and division on the array elements. Example The following example demonstrates finding the average of three numbers using an array: p...
