js sort strings code example

Example 1: javascript order by string array

users.sort((a, b) => a.firstname.localeCompare(b.firstname))

Example 2: sort a string in javascript

var string='ACBacb';
var sortedString = string.split('').sort().join('');

Example 3: 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 4: string sort javascript

var names = ["Peter", "Emma", "Jack", "Mia"];
var sorted = names.sort(); // ["Emma", "Jack", "Mia", "Peter"]
