Objects

Intro

You have already learned that Kin variables are containers for data values.

This code assigns a simple value (Fiat) to a variable named car:

reka car = "Fiat"

Objects are variables too. But objects can contain many values.

This code assigns many values (Fiat, 500, white) to a variable named car:

const car = {
  type:"Fiat",
  model:"500",
  color:"white"
}

The values are written as name:value pairs (name and value separated by a colon).

Object Definition

You define (and create) a Kin object with an object literal:

reka person = {
  firstName:"John",
  lastName:"Doe",
  age:50,
  eyeColor:"blue"
};

# This is the same as:
reka person = {firstName:"John", lastName:"Doe", age:50, eyeColor:"blue"};

Spaces and line breaks are not important. An object definition can span multiple lines:

Object Properties

The name:values pairs in Kin objects are called properties:

Property | Property Value

firstName | John lastName | Doe age | 50 eyeColor | blue


Accessing Object Properties

You can access object properties in two ways:

objectName.propertyName

Or

objectName["propertyName"]

Object Methods

A method is a function stored as a property.

Ex:

porogaramu_ntoya add (a, b) {
  tanga a + b
}

reka obj = {
  method: add
}

In this case our object obj has a method named method which can perform addition of two numbers.

Noticide that we didn't declare method inside and object? This is because in Kin we don't support declaring methods inside objects. We can only assign a function to a property of an object.

Accessing Object Methods

You access an object method with the following syntax:

obj.method()

If you access a method without the () parentheses, it will return the function definition:

reka add = obj.method
