JavaScript calculates the maximum value of elements in an array
Request:
Find the maximum value in the array [2, 6, 1, 7, 52, 25, 7].
The idea of realization is:
Declare a variable max that holds the largest element
The default maximum value max is defined as the first element in the array, arr [0]
Iterate through the array and compare each array element with max
If the array element is greater than max, store the array element in max, otherwise continue to the next round of comparison
Finally, output this max
Code implementation: var arr = [2, 6, 1, 77, 52, 25, 7, 99]; var max = arr [0]; for (var I = 1; I < arr.length; iTunes +) {if (max < arr [I]) {max = arr [I];}} console.log (max); output: 99 function version: code implementation: / / use function to find the maximum value in the array [3,77,44,99,143]. Function getArrMax (arr) {/ / arr accepts an array arr = [3,77,44,99,143] var max = arr [0]; for (var I = 1; I < arr.length; iTunes +) {if (max < arr [I]) {max = arr [I];}} return max;} / / getArrMax ([3,77,44,99,143]) / argument is an array var re = getArrMax ([3,77,44,99,143]); console.log (re); output: 143Function arguments: code implementation: function getMax () {var max = arguments [0]; for (var I = 1; I < arguments.length; iTunes +) {if (max < arguments [I]) {max = arguments [I];} return max } console.log (getMax (1,2,3)); console.log (getMax (1,2,3,4,5)); console.log (getMax (11,2,34,444,5100)); output: more than 35444 is all the content of the article "how to find the maximum value of javascript array".
