Example 1: who to accses to an object vallue inside an array with .filter method js
const array = [
{
username: "john",
team: "red",
score: 5,
items: ["ball", "book", "pen"]
},
{
username: "becky",
team: "blue",
score: 10,
items: ["tape", "backpack", "pen"]
},
{
username: "susy",
team: "red",
score: 55,
items: ["ball", "eraser", "pen"]
},
{
username: "tyson",
team: "green",
score: 1,
items: ["book", "pen"]
},
];
//FILTER MEMBERS IN TEAM "RED"
const filterArray=array.filter(word=>word.team==="red")
Example 2: filter javascript array
var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
const result = words.filter(word => word.length > 6);
console.log(result);
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: filter 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]
or
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 5: js filter array
const filterArray=(a,b)=>{return a.filter((e)=>{return e!=b})}
let array = ["a","b","","d","","f"];
console.log(filterArray(array,""));//>> ["a","b","d","f"]
Example 6: filter
const array = [-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13];
function isPrime(num) {
for (let i = 2; num > i; i++) {
if (num % i == 0) {
return false;
}
}
return num > 1;
}
console.log(array.filter(isPrime)); // [2, 3, 5, 7, 11, 13]
