Introduction Execution context is an abstract concept describing the environment within which JavaScript code is executed. The execution context will dictate if a variable, object, or another block of code is accessible or not. There are two types of execution contexts: global and function. Let’s examine the global execution context first. Global execution context The global execution context is the default execution context. Variables and
Pre-Launch It’s been a busy 2 days, I pre-launched the JavaScript Technical Interview Guide and have sold 50% of the early bird copies. I made an announcement on Twitter and on Reddit. So far 280 upvotes on Reddit! Anyways keep reading – the juice is down below! So far I’ve emailed subscribers once with 80 practice coding exercises from chapter 1 (The Basics) . Besides
Introduction Hi devs especially junior devs! For the past 5 months I’ve been super focused on writing a technical interview guide for juniors who want to break into the web-development industry. Since a solid grounding in JavaScript is paramount to clearing interviews focused on web applications, I wanted to write a guide that would help junior developers learn and practice at the same time. Why?
Introduction Since we’re using Unity3D to build our VR experiences, here are the steps to walk through finishing setting up Unity3D for VR. It requires extra components as you’re building for the Quest. Steps Download and install Unity hub here. Unity Hub is like your dashboard to manage your Unity projects and any Unity3D versions that you install Choose the latest version of Unity3D to
This past month I’ve been working with an animation studio in Utah to help create a course on JavaScript for kid! It’s been a lot of fun! See the trailer here!
Request the user to start their webcam stream var video= document.querySelector(“#videoElement”); if(navigator.mediaDevices.getUserMedia){ navigator.mediaDevices.getUserMedia({ video: true }) .then(function (stream) { video.srcObject = stream; }) .catch(function (error) { console.log(“Error streaming”); }); } Using the getUserMedia() API which allows you to access a user’s camera and mic without any plugins Streams have inputs (video) and outputs (video) The if-conditional checks if the getUserMedia is supported Syntax: navigator.mediaDevices.getUserMedia(constraints).then(successCallback).catch(errorCallback) The
Level 1 of Bootstarry is almost complete, a few glitches and narration is missing but it’s starting to shape up. I’ve moved from Unreal Engine to Unity3D for now which means dipping into C# which is ok because I find that better than the flowchart type system that UE4 engine has (blueprints) which makes game development seem a bit magical.
Amidst a global pandemic (Covid- 19), I will be sitting quietly like a farm mouse and write a book with a publisher called Packt. The book will be focused on JavaScript interview questions in the form of practical coding questions.
forEach() ES6 has introduced the forEach() method which allows you to loop through an array. Arrays as you may already know are of the type ‘object’. In contrast to the string,number,boolean, undefined and symbol types which are primitive data types. For example if we console.log the typeof operator to find the typeof array, objectwill be logged, as seen below: const yummies = [‘Ice-cream’,’Cupcake’,’Donut’,’Cupcake’]; console.log(typeof yummies)//
