filterNonUnique

Filters out the non-unique values in an array.

Use Array.filter() for an array containing only the unique values.

const filterNonUnique = arr => arr.filter(i => arr.indexOf(i) === arr.lastIndexOf(i));
 
filterNonUnique([1, 2, 2, 3, 4, 4, 5]); // [1,3,5]

findLast

Returns the last element for which the provided function returns a truthy value.

Use Array.filter() to remove elements for which fn returns falsey values, Array.slice(-1) to get the last one.

const findLast = (arr, fn) => arr.filter(fn).slice(-1)[0];
+

findLast

Returns the last element for which the provided function returns a truthy value.

Use Array.filter() to remove elements for which fn returns falsey values, Array.pop() to get the last one.

const findLast = (arr, fn) => arr.filter(fn).pop();
 
findLast([1, 2, 3, 4], n => n % 2 === 1); // 3

findLastIndex

Returns the index of the last element for which the provided function returns a truthy value.

Use Array.map() to map each element to an array with its index and value. Use Array.filter() to remove elements for which fn returns falsey values, Array.slice(-1) to get the last one.

const findLastIndex = (arr, fn) =>
   arr
