This intl.collator.prototype.compare() method basically used to make the comparison between two strings as per the sorting order of the collator object.
Here the compare-getter function gives a number as first-string and second-string compared between two strings as per the sorting order of the collator object, It shows a value less than 0 if the first string comes before the second string, shows a value greater than 0 if the first string comes after the second string and 0 if both the parametric strings are equalized.
Syntax:
collator.compare(firststring, secondstring)
Parameters: This method will take two strings (firststring, secondstring) as input parameters to make the comparison between them.
Example 1: For sorting array using compare-getter function which is bounded to follow the collator which further passed directly to Array.prototype.sort().Â
Javascript
<script>   var x = ['Geeks', 'Geeksfor', 'GFG', 'courses', 'java'];   var collator = new Intl.Collator('de-u-co-phonebk');     // Using collator compare function   x.sort(collator.compare);   console.log(x.join(', ')); </script> |
Output:Â
courses, Geeks, Geeksfor, GFG, java
Example 2: Also use the compare-getter function to search the matching strings between the given parametric strings. Let’s see how:
Javascript
<script>   var x = ['GFG-for-GFG', 'stress', 'Care', 'surprise', 'gfg'];   var collator = new Intl.Collator('fr',                      { usage: 'search', sensitivity: 'base' });     var srch = 'gfg';   var mtchs = x.filter(n => collator.compare(n, srch) === 0);   console.log(mtchs.join(', ')); </script> |
Output:Â
gfg
