How to use Intl.Collator for Advanced String Sorting In Typescript
The Intl.Collator object enables more sophisticated string comparisons than localeCompare. It can handle case sensitivity, diacritics, and other locale-specific sorting rules more effectively. This is particularly useful for internationalized applications where proper sorting according to user locale is necessary.
Example: We’ll sort an array of objects by their name property using Intl.Collator. This approach ensures that the sorting respects locale-specific rules more accurately than localeCompare.
interface MyObject {
id: number;
name: string;
}
const objects: MyObject[] = [
{ id: 2, name: 'Beta' },
{ id: 1, name: 'Alpha' },
{ id: 3, name: 'Gamma' }
];
// Create a collator with specific options
const collator = new Intl.Collator('en', { sensitivity: 'base', ignorePunctuation: true });
objects.sort((a, b) => collator.compare(a.name, b.name));
console.log(objects);
Output:
[
{ "id": 1, "name": "Alpha"},
{ "id": 2, "name": "Beta"},
{ "id": 3, "name": "Gamma"}
]
How to Sort Objects in an Array Based on a Property in a Specific Order in TypeScript ?
Sorting objects in an array based on a specific property is a common task in software development. TypeScript, with its static typing and powerful features, provides various approaches to accomplish this task efficiently. The below approaches can be used to sort an array of objects in properties.
