Javascript Example

Here’s an example of what the code above looks like in Javascript.

%%javascript
var possesions = {
  owner: "Lil Bro",
  dollars: 50,
  food: ["apps", "pizza", "banana"],
};

console.log(possesions);
// -> { owner: "Lil Bro", dollars: 50, food: ["apps","pizza","banana"] }
possesions.food[2] = "half-eaten banana";
console.log(possesions.food);
// -> [ "apps", "pizza", "half-eaten banana" ]
possesions.dollars = possesions.dollars / 2;
console.log(possesions.dollars);
// -> 25

console.log(JSON.stringify(possesions));
// -> {"owner":"Lil Bro","dollars":25,"food":["apps","pizza","half-eaten banana"]}
