![]() ![]() It starts by setting the maximum value to the first value in the array, and the maximum value index to 0. This code is an example of how to find the maximum value in an array. const arr = Ĭonsole.log("Maximum value is: " + max_val) Ĭonsole.log("Maximum value index is: " + max_index) This process will continue until the end of the array is reached, at which point the index of the max value will be returned. If the value is greater than the current max, it will update the max and its index. ![]() This method will loop through the array and compare each value to the current max value. If you need to find the index of the max value in an array, you can do so using a for loop in Javascript. Live Demo Solution 2: Find the index of max value in the array using For loop const arr = Ĭonst max_value = (null, arr) Ĭonst max_index = arr.indexOf(max_value) Ĭonsole.log("Max index is: " + max_index) If you do not want to use the spread operator inside Math.max() function, you can use () function and pass null as the first parameter and array as the second parameter. Finally, the index of the max value is found using the indexOf() function. Then, the max value in the array is found using the Math.max() function. This code defines an array called arr and assigns it integer values. We can write this in one line using the below code: arr.indexOf(Math.max(.arr)) Syntax Array.indexOf(Math.max(.Array)) Ĭonst arr = Ĭonsole.log("Max value index is: " + max_index) By using Math.max() and indexOf() together, we can easily find the index of the max value in an array. ![]() The spread operator allows us to spread the elements of an array out into individual values, which makes it easier to work with them. ![]()
