Return the maximum number in each array using map JavaScript
We have an array of arrays of Numbers like this one −
const arr = [ [12, 56, 34, 88], [65, 66, 32, 98], [43, 87, 65, 43], [32, 98, 76, 83], [65, 89, 32, 54], ];
We are required to write a function that maps over this array of arrays and returns an array that contains the maximum (greatest) element from each subarray.
Therefore, let’s write the code for this function −
Example
const arr = [ [12, 56, 34, 88], [65, 66, 32, 98], [43, 87, 65, 43], [32, 98, 76, 83], [65, 89, 32, 54], ]; const findMax = arr => { return arr.map(sub => { const max = Math.max(...sub); return max; }); }; console.log(findMax(arr));
Output
The output in the console will be −
[ 88, 98, 87, 98, 89 ]
