js fillter code example
Example 1: 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);
Example 2: javascript filter array of objects
function isBigEnough(value) {
return value >= 10
}
let filtered = [12, 5, 8, 130, 44].filter(isBigEnough)
// filtered is [12, 130, 44]
