Natural Array Element Sorting: Strings with Numbers
This article delves into the task of sorting arrays containing elements that combine strings and numbers in a natural order, where numerical sequences within the strings should be considered in the sorting process.
The Problem
Consider an array like this:
1 |
|
If we attempt to sort this array using a conventional sort function, we may end up with an incorrect order:
1 |
|
The Solution: Natural Sorting
To achieve natural sorting, we can leverage the following JavaScript function:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
|
This function tokenizes the input strings into arrays of numerical and non-numerical values. It then compares the arrays lexicographically, taking into account the numerical values as integers and the non-numerical values as strings.
Example
Applying this function to the given array results in the desired natural sorting order:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
|
This produces the following sorted array:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
|
