Removes and returns every extra instance of unique items in array.
NOTICE: The function will error if array contains an object.
'object' does not include arrays. Arrays are OK.
let arr = [1, 2, 3, 4, 1, 2, 3, 4, 5, 2]; let duplicates = getAndRemoveDuplicates(arr); // arr is now [1,2,3,4,5]. // duplicates is now [1,2,2,3,4] // (In returned duplicates, identical items are always side-by-side) let arr = [1, 2, ['a','b'], 9, 1, 2, 3, 4, ['a','b'], 1, 9, ['a','b']]; let duplicates = getAndRemoveDuplicates(arr); // arr is now [1, 2, ['a','b'], 9, 3, 4] // duplicates is now [1, 1, 2, ['a','b'], ['a','b'], 9] // This will trigger error, because arr contains object: let arr = [1, 2, {prop:1}, 2, 3, 4]; getAndRemoveDuplicates(arr); // Error! npm install @writetome51/array-get-and-remove-duplicates
// If using TypeScript: import {getAndRemoveDuplicates} from '@writetome51/array-get-and-remove-duplicates'; // If using ES5 JavaScript: var getAndRemoveDuplicates = require('@writetome51/array-get-and-remove-duplicates').getAndRemoveDuplicates;
