This year my contracts have ranged from curriculum building, making games in Unity3D, Minecraft and Roblox. I have also done some code fixer uppers based on vanilla JavaScript, as I’m a vanilla JS fan girl and web dev contracts making small webapps. As you can imagine it involves quite a bit of brain agility. Though I compartmentalize my work so at no point do I
In JavaScript functions are a type of object known as function object. You can work with function objects as though they were objects. Functions may be assigned to objects, passed in as arguments to other functions, returned from other functions. Additionally a function can be passed into an array. And this gets me to earlier in my articles when I’ve stated “almost everything in JavaScript
Setters in JavaScript. Check out parts 1 and 2 Setters in JavaScript There are three ways you can use setters: 1. Default method syntax 2. get keyword 3. Object.defineProperty() method We will now discuss the above three in detail. 1. Default method syntax The default method syntax can also be used for setters. Setters will set the property of the object to the value passed
carrying on from part 1 .. Getters in JavaScript Getters are functions that retrieve a value from static properties from an external source. You can only access properties and cannot access methods as they are functions of an object or class and are not static. There are three ways you can use getters and setters: 1. Default method syntax 2. get keyword 3. Object.defineProperty() method
Classes In object-oriented programming, class types are templates for creating objects. As we just learned that in prototypal inheritance, objects inherit properties and methods from a prototype. Classes build upon prototypal inheritance. Classes were introduced in ES6 to mimic the class data type found in Java and other object-oriented programming languages. Till now developers used constructor functions to mimic object-oriented design patterns. JavaScript does not
Accessors: Getters and Setters This is part 1 of a brief introduction to getters and setters in JavaScript. Getters and Setters are ES5 features. Objects have two types of properties: Static data property Accessor property So far we have come across static data properties in the objects that we have been making. For example: let blackLivesMatter = { status: true, usecase: ‘daily’ } In this
Playing around with MRTK here It’s a nice succinct tutorial on setting up an XR project and manipulating objects with ObjectManipulator
Break and continue statements The break statement is used to exit a loop completely once a condition has been met, or after x number of iterations. As such it is commonly used within an if conditional block. Take as an example the following code: for (let i = 0; i <= 5; i++){ console.log(i); } This will print out the value of variable i from
Copying objects with deep copy The JSON.stringify and JSON.parse methods can be used to deep copy an object. In a deep copy, the source and target objects have different memory addresses and are not connected at all. The JSON.stringify() method will take a JavaScript object as an argument and transform it into a string. Then the JSON.parse() method will parse the JavaScript string and return
Copying objects with Shallow copy Now that we went over shallow and deep copies in part 1, let’s go over shallow copying in JavaScript. There are 3 ways to create shallow copies in JavaScript: Iteration using for key in an object Spread operator Object.assign() 1. Iteration using for key in an object In order to copy the items of an object into another object we
