JavaScript filter elements 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: 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 3: array filter

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 4: JavaScript Array Methods .filter()

const colours = ['green', 'black', 'dark-orange', 'light-yellow', 'azure'];
// a 6 karakternél hosszab színekre szűrünk:
const result = colours.filter(colour => colour.length > 6);
console.log(result);
// --> [ 'dark-orange', 'light-yellow' ]
