Sorting Array In Different Languages JavaScript, Ruby, Python

#javascript #python #ruby #webdev

Some time when we solve any kind of problem we need to sort the data before perform the operation on the data every programming language provide some predefined methods to sort the data or element in ascending or descending order.

arr[] = {4,2,5,7,3,8,1}
Enter fullscreen mode Exit fullscreen mode

Sort in Ascending Order

arr[] = {1,2,3,4,5,7,8};
Enter fullscreen mode Exit fullscreen mode

Sort in Descending Order

arr[] = {8,7,5,4,3,2,1};
Enter fullscreen mode Exit fullscreen mode
Javascript

To sort number and string in JavaScript both have different manner.Sort the number in JavaScript.

let arr = [4,2,5,7,3,8,1]

arr.sort((a,b)=>{return a-b})

console.log(arr)

//1,2,3,4,5,7,8
Enter fullscreen mode Exit fullscreen mode

Sort the string in JavaScript is too easy you just have to call sort method.

let string_arr = ['ad', 'ds', 'ar', 'ee']

string_arr.sort( ( a, b )  => a.localeCompare( b ) );

console.log(string_arr);

//'ad', 'ar', 'ds', 'ee'
Enter fullscreen mode Exit fullscreen mode
Ruby

Sort numbers in the ruby with the help of sort method.

arr = [3,5,4,66,22,34,12]

arr.sort!

#[3, 4, 5, 12, 22, 34, 66]

string_arr = ['ad', 'ds', 'ar', 'ee']

string_arr.sort!

#["ad", "ar", "ds", "ee"]
Enter fullscreen mode Exit fullscreen mode
Python

Sort numbers in the python with the help of sort method.

arr = [3,5,4,66,22,34,12]

Your first JS Sample has a wrong Array Declaration

let myArr = [ 4,2,5,7,3,8,1 ]
myArr.sort( ( a, b ) => a-b )
console.log (myArr )
Enter fullscreen mode Exit fullscreen mode

The second example is bad because it doesn't take local circumstances

better:

let string_arr = ['ad', 'ds', 'ar', 'äd' ,'ee']
string_arr.sort( ( a, b )  => a.localeCompare( b ) );
console.log(string_arr);
Enter fullscreen mode Exit fullscreen mode
