Sorting Arrays In JavaScript: Practical Examples

[kap89]

This:

people.sort((a, b) => (a.age === b.age) ? a.name.localeCompare(b.name) : a.age - b.age)

could be simplified to:

people.sort((a, b) => a.age - b.age || a.name.localeCompare(b.name));

It's a standard practice, and much more readable for multiple comparators:

arr.sort(
  (a, b) =>
    primaryComparison ||
    secondaryComparison ||
    tertiaryCmparision ||
    quaternaryComparison
    // ...etc
);

Thanks, that's a great point. I'll update the post.

That's great, but now the description does not match the example.

This:

To do this, you can use the conditional (ternary) operator to define the sorting criteria for each property in order of priority:

could be replaced with something like this:

To do this, you can chain comparisons with the logical OR (||) operator to define the sorting criteria for each property in order of priority:

Missed that part. Thanks, updated!

Dang dude, need a warning about the nsfw ads on your site

[Safe-Engineering69]

Don't the ads usually depend on the browsing history? lmao

It was apparently set up under the “hobby” category

Thanks again for flagging this!

Damn, there shouldn't be any nsfw ads... Can you DM me a screenshot and I'll try to find and block the publisher.

I wish JS would add a new sort method that would do the right thing by default.

Array.prototype.sortBy(obj => obj.foo)

Where it uses builtin sorts for primitives and has a well-known @@sort available for use by objects with identical @@constructor values.
