Objects

Objects in Algo are similar to objects in JavaScript, but with a twist. To create a simple object, you do the following:

let x = object
{
    //insert your properties here :)
};

Note that defining an object also requires a trailing semicolon, unlike libraries and other braced structs.

Once you've defined an object, you can add properties to it, like so:

let x = object { ... };
x.foo = 3;
x.bar = 2;

If you attempt to access a property that doesn't exist, it will simply return null. You can also define object properties with the definition of the object, instead of doing it after creation. This is great for objects with known structures.

let x = object
{
    let y = 3;
    let z = [];
};
print x.y; //3
print x.z; //empty list

You can also define functions within objects, within which you can access the scope of the object, like so.

Note: This object won't be able to be serialized with the json library until all functions are stripped out.

let x = object
{
    let counter = 0;
    let increment() = 
    {
        counter++;
    }
}

print x.counter; //0
x.increment();
print x.counter; //1

Objects are always mutable, and can have properties added and removed from them using let and disregard at any time. You can also serialize and deserialize objects from JSON using the json standard library! Here's a quick example of that:

import "json";
let x = object
{
    let y = [1, 2, 3];
    let z = "string!";
};

//serialize
let jsonString = json.make(x);

//deserialize
let x_again = json.parse(jsonString);
