Checks if all elements in an array are unique. Create a new Set from the mapped values to keep only unique occurrences. Use Array.prototype.length and Set.prototype.size to compare the length of the unique values to the original array. Source https://www.30secondsofcode.org/js/s/all-unique

Insert an element before another one. Call the before() method on the reference node, and pass in the new node as an argument. Source https://vanillajstoolkit.com/reference/dom-injection/element-before/

If you want to deep clone a value in Node.js, you no longer need to use a library or the JSON.parse(JSON.stringify(value)) hack. You can use the new global function structuredClone() Source https://github.com/roeib/JavaScript-snippets#structuredclone

The original way to add elements to the DOM.

You can also use it to inject an element after another one by using the .nextSibling property on your referenceNode. Source https://vanillajstoolkit.com/reference/dom-injection/element-insertbefore/

Removes falsy values from an array. Use Array.prototype.filter() to filter out falsy values (false, null, 0, “”, undefined, and NaN). Source https://www.30secondsofcode.org/js/s/compact
