Javascript Objects

One can think of a javascript objects as containers with collections of data in it. Each data has a property name or key, with an assigned value (key-value pairs).  These values can be of primitive types, functions, objects, etc. When the value of a pair is a function, we call this a method. Behind the scenes, when an object is created and properties and values/methods are added to it, the object stores references to these for later access. This means that objects can store references to other objects.

There are a few ways we can create objects in javascript. We can use object literals, constructor functions, the Object.create method and we can use ES6 classes to create objects as well. Read More

Gulp – Getting Started With Javascript Build Automation

Gulp helps us automate tasks within your javascript projects. Why would we want to do this? Well it helps us to be more productive. Not only do frontend developers have to sit down and write code, there is a ton of other work we have to do. Things like minification, concatenation, writing vendor prefixes, using LESS to compile CSS, optimizing third-party code like jQuery, Angular etc, injecting files into HTML, unit testing, caching templates, file revisions and versioning, code analysis, and the list goes on and on. As you can already tell, frontend development is no joke when done right. And here is where Gulp comes in.

Getting Started With Webpack

On a basic level, webpack is a build tool.  A build can be described as converting source code files into standalone artifacts that can be run on a computer. What webpack does, is bundle modules used within a frontend application into a single file. So what does this have to do with javascript? When working with javascript, there are certain tasks that you do on a regular basis (especially if you are building a large scale application). Things like file concatenating and minification of javascript and CSS files, running tests, linting etc. The reasons why we do these is so our javascript applications are performant. By having a build step we can solve issues like multiple web requests, code file size, file order dependencies, code syntax checking(linting) and many more. Having a build step mitigates these problems related to development. Read More

Bower Fundamentals

As a frontend developer, there is one thing you cannot escape from. That is integrating third party libraries into your project. Need to use jQuery, Underscore, Bootstrap? You have to download their libraries. Our applications are a full of these imported libraries. They help us to get our day to day tasks done quickly and effectively. In this post we will be talking about Bower.

What Bower does is help us quickly get those libraries into our projects, which drastically reduces time needed to go to third party sites to download them (involves many manual steps). Using the command line, we can delegate that tasks to bower and it will get all the files we need into our project, ready to be used.  Read More
