January 04, 2020
Filters an array’s values based on a predicate function, returning only values for which the predicate function returns true
.
Use Array.prototype.filter()
in combination with the predicate function, pred
, to return only the values for which pred()
returns true
.
const reject = (pred, array) => array.filter((...args) => !pred(...args));
reject(x => x % 2 === 0, [1, 2, 3, 4, 5]); // [1, 3, 5]
reject(word => word.length > 4, ['Apple', 'Pear', 'Kiwi', 'Banana']); // ['Pear', 'Kiwi']
