JavaScript Array Methods .find()

Comment

const list = [5, 12, 8, 130, 44];
// a find metóduson belül a number egy paraméter
// azért nem szükséges köré a zárójel, mert csak egy paramétert adunk át
// minden más esetben így kell írni:
// const found = list.find((index, number) => number > index);
const found = list.find(number => number > 10);
console.log(found);
// --> 12

javascript find method

Comment

var evens = _.filter([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
=> [2, 4, 6]

Looks through each value in the list, returning a new array of all the values that pass a truth test (predicate). predicate is transformed through iteratee to facilitate shorthand syntaxes.
