javascript filter array method code example

Example 1: filter javascript array

var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = words.filter(word => word.length > 6);

console.log(result);

Example 2: .filter js

const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = words.filter(word => word.length > 6);

console.log(result);
// expected output: Array ["exuberant", "destruction", "present"]

Example 3: how the filter() function works javascript

const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];

const filter = arr.filter((number) => number > 5);
console.log(filter); // [6, 7, 8, 9]

Example 4: array.filter in js

var numbers = [1, 3, 6, 8, 11];

var lucky = numbers.filter(function(number) {
  return number > 7;
});

Example 5: does filter change original array

Note: filter() does not change the original array.
