Script Preparation code:
​x
 
var a = "z11";
var b = "z1";
var expectedOrder = 1;
​
var options = {
    sensitivity: 'base',
    numeric: true,
};
​
var collator = new Intl.Collator(undefined, options);
Tests:

  • localeCompare

     
    a.localeCompare(b, undefined, options) === expectedOrder

  • Intl.Collator().compare

     
    new Intl.Collator(undefined, options).compare(a, b) === expectedOrder

  • collator.compare

     
    collator.compare(a, b) === expectedOrder
