• Memory values
• Commands params
• Integration input params (if needed - it depends on the integration type)

More complex code

If you wish to write more complex code that contains assignments, loops or functions, you have to put it in a function using this exact snippet:

(function() {
   // put your code here
   // remember to return the result
 })()

(function() {
   const fruitArray = [{name: "Apple", price: 10}, {name: "Grape", price: 5}, {name: "orange", price: 15}];
   const moreFruitsArray = [...fruitArray, {name: "lemon", price: 2}];
   const onStockFruits = moreFruitsArray.map(el => ({...el, available: true}));
   
   const  prettyPrint = (fruit) => {
     return "Fruit: " + fruit.name + " price: " + fruit.price + " on stock: " +fruit.available;
   };
   
   return onStockFruits
     .map(prettyPrint)
     .join("\n");
 })()

Fruit: Apple price: 10 on stock: true
Fruit: Grape price: 5 on stock: true
Fruit: orange price: 15 on stock: true
Fruit: lemon price: 2 on stock: true
