filter value in array javascript code example

Example 1: .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 2: filter in js

const filterThisArray = ["a","b","c","d","e"] 
console.log(filterThisArray) // Array(5) [ "a","b","c","d","e" ]

const filteredThatArray = filterThisArray.filter((item) => item!=="e")
console.log(filteredThatArray) // Array(4) [ "a","b","c","d" ]

Example 3: array.filter in javascript

//Eg 1 - If item is unchecked, remove it from array

const array = [2, 3, 4]

if (event.target.checked) {
      newValue.push(option);
    } else {
      newValue = newValue.filter(item => item.id != option.id);
    }

//If false, it will remove the element. 2 is not equal to 2.

//Eg 2 - To return an array with length > 6

const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
const result = words.filter(word => word.length > 6);
