Sort Custom Collections Randomly

[scottwater]

Any suggestions for sorting a collection randomly?

I thought this would work:

  eleventyConfig.addCollection("caps", collection => {
    return collection.getFilteredByTag("gmk").sort((a, b) => Math.random());
  });

But it is still sorting them alphabetically (no dates are available).

Thanks, Scott

Math.random() returns a float between 0.0 and 1.0, so it probably won’t affect the default sort order. You could try something like subtracting 0.5 so you get a number between -0.5 and +0.5, per https://javascript.info/task/shuffle (click “solution” button).

Or, if you’re using nunjucks and want a single random element from an array/collection there is a random filter.

That did the trick. Thanks for the tip and explanation.
