Max & Min Array Value/ Sum Arr Value/Average Arr Value/Odd Arr Value.
To solidify knowledge with Array method and for clear understanding of the JS’s array. I’ve wrote some example.
//Max Min value of array //using sort() method with compareFunction as argument and // min(),max() method of Math object.
var arr = [5,34,545,44,4,3,8, -5, -1, -22]; var maxValueArr = arr.sort(function(a, b){return b-a}); document.write("Max value of array with <b>sort</b> method: " + maxValueArr[0] + "</br>"); document.write("Max value of array with <b>max()</b> method: " + Math.max.apply(null, arr) + "</br>"); var minValueArr = arr.sort(function(a,b){return a - b}); document.write("Mix value of array with <b>sort</b> method: " + minValueArr[0] + "</br>"); document.write("Max value of array with <b>min()</b> method: " + Math.min.apply(null, arr) + "</br>"); //sum of all array's values var sumArrValue = 0; for(var i = 0; i < arr.length; i++){ sumArrValue += arr[i]; } document.write("Sum of all array's values: " + sumArrValue + "</br>"); // average value of array var avgArrValue = Math.round(sumArrValue / arr.length); document.write("Average array value: " + avgArrValue + "</br>"); //odd value of array document.write("Odd value of array: "); for(var x = 0; x < arr.length; x++){ var oddValue = arr[x] % 2 !== 0; if(oddValue){ document.write( arr[x] + " "); } }
