Object

The Object type represents a collection of key-value pairs. Objects in this language are similar to JavaScript objects.

Syntax​

Objects are created using curly braces ({}), with key-value pairs separated by commas. Keys must be strings (or string-like), and values can be of any type.

const obj = { key1: "value1", key2: "value2" };

Accessing and modifying elements​

You can access values in an object using either dot notation or bracket notation.

Dot Notation

// read
const value1 = obj.key1;  // "value1"

// write
obj.key1 = "newValue1";

Bracket notation

// read
const value2 = obj["key2"];  // "value2"

// write
obj["key2] = "newValue2";

⚠️ Only use these notations when you know that the element exists, otherwise an internal exception will be thrown! (see .contains())

Safely accessing elements​

Check that the element exists by using the .contains() method.

if(obj.contains("key2"))
    console.log(obj["key2"]);

Adding new properties​

You can add new properties by using the .set() method.

obj.set("key3", "value3"); // add "key3" with the value of "value3".
obj.set("key3", "newValue3"); // if the key already exists, then it will edit the value instead.

Removing properties​

You can remove properties by using the .remove() method.

const wasRemoved = obj.remove("key3"); // remove key3 if it exists

if(wasRemoved)
    console.log("key3 was removed!");
