sorting an array in js code example
Example 1: sorting array from highest to lowest javascript
// Sort an array of numbers
let numbers = [5, 13, 1, 44, 32, 15, 500]
// Lowest to highest
let lowestToHighest = numbers.sort((a, b) => a - b);
//Output: [1,5,13,15,32,44,500]
//Highest to lowest
let highestToLowest = numbers.sort((a, b) => b-a);
//Output: [500,44,32,15,13,5,1]
Example 2: sort javascript array
var points = [40, 100, 1, 5, 25, 10];
points.sort((a,b) => a-b)
Example 3: sorting of arraray's number element in javascript
let numbers = [0, 1, 2, 3, 10, 20, 30];
numbers.sort((a, b) => a - b);
console.log(numbers);
Example 4: sort js array array
var ages = [18, 21, 9, 41, 35, 24]
ages.sort(function(a, b) {
return a - b
})
// => [9, 18, 21, 24, 35, 41]
Example 5: array sort js
arr = ['width', 'score', done', 'neither' ]
arr.sort() // results to ["done", "neither", "score", "width"]
arr.sort((a,b) => a.localeCompare(b))
// if a-b (based on their unicode values) produces a negative value,
// a comes before b, the reverse if positive, and as is if zero
//When you sort an array with .sort(), it assumes that you are sorting strings
//. When sorting numbers, the default behavior will not sort them properly.
arr = [21, 7, 5.6, 102, 79]
arr.sort((a, b) => a - b) // results to [5.6, 7, 21, 79, 102]
// b - a will give you the reverse order of the sorted items
//this explnation in not mine
Example 6: sort function explained javascript
var sortedArray = myArray.sort(function(a,b){
if (a.name < b.name)
return -1;
else if (a.name == b.name)
return 0;
else
return 1;
});
