array js sort code example

Example 1: sort javascript array

var points = [40, 100, 1, 5, 25, 10];
points.sort((a,b) => a-b)

Example 2: 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 3: javascript sort array

var points = [40, 100, 1, 5, 25, 10];

points.sort(function(a, b){return a - b});

Example 4: sort array javascript

let numbers = [5, 2, 8, 1, 4, 6, 3, 7]
numbers.sort() // sorts the numbers ascending: [1, 2, 3, 4, 5, 6, 7, 8]
