This article mainly introduces javascript how to find the maximum value of the array, the article is very detailed, has a certain reference value, interested friends must read it!

Javascript to find the maximum value of the array method: 1, declare a save the largest element of the variable max;2, traverse the array and compare each array element with max; 3, when the array element is greater than max, the array element is stored in max; 4, output max.

This article operating environment: windows7 system, javascript1.8.5 version, DELL G3 computer

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".
