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

how to sort an array in javascript
you can sort array in different ways:
first....by using the sort method
ex: let arr = ["a", "d", "b", "c", "f"]
let res = arr.sort()
NOTE: this method is not ideal
second...... by using the sort function
ex: let arr = [1, 10, 11, 30, 100, 50, 45]
let res = arr.sort((a, b)=> a - b ).....this sorts in ascending order
let res = arr.sort((a, b)=> b - a ) ...this sorts in descending order
NOTE: we can also user different algorithms to sort an array. example: bubble sort,
quick sort, merge sort etc.

how to sort an array
var carBrands = ["Toyota", "Jeep", "Ford", "Volvo"];
carBrands.sort();
// array.sort() method sorts an array in ascending order by default
// extend the function like below to sort in descending order or customize
//carBrands.sort(function(a, b){return b-a});
