JavaScript: Tips of the Day
Returns all unique values of an array, based on a provided comparator function
Example:
const tips_uniqueElementsBy = (arr, fn) => arr.reduce((acc, v) => { if (!acc.some(x => fn(v, x))) acc.push(v); return acc; }, []); console.log(tips_uniqueElementsBy( [ { id: 0, value: 'p' }, { id: 1, value: 'q' }, { id: 2, value: 'r' }, { id: 1, value: 's' }, { id: 0, value: 't' } ], (a, b) => a.id == b.id ));
Output:
[[object Object] { id: 0, value: "p" }, [object Object] { id: 1, value: "q" }, [object Object] { id: 2, value: "r" }]
