}better way to do nested if statements javascipt
/_ return early when invalid conditions found _/
function test(fruit, quantity) {
const redFruits = ['apple', 'strawberry', 'cherry', 'cranberries'];
if (!fruit) throw new Error('No fruit!'); // condition 1: throw error early
if (!redFruits.includes(fruit)) return; // condition 2: stop when fruit is not red
console.log('red');
// condition 3: must be big quantity
if (quantity > 10) {
console.log('big quantity');
}
