Array methods at a glance

js

// The filter() method creates a new array filled with elements that pass a test provided by a function
[1, 2, 3, 4, 5].filter((n) => n > 3); // [4,5]

// The find() method returns the value of the first element that passes the test
[1, 2, 3, 4, 5].find((n) => n > 3); // 4

//. The every() method tests whether all elements in the array pass the test implemented by the provided function. It returns a Boolean value.
[1, 30, 39, 29, 10, 34].every((n) => n < 40); // true
