Caching in NodeJS with Redis
Speed performance is critical in modern day applications. Most of the times your application may have to make requests to an endpoint/server to get some data. Or your application may frequently request a specific dataset. Depending on the size of your dataset a long with other things like query database and network speed, the speed at which your application can fetch certain data to display to users may get slower over time (as data increases). This is where caching comes in handy and can dramatically improve your application's speed.
JS call, bind, and apply methods
Each JavaScript function has access to the this keyword. The this keyword references the object to which the function belongs (remember, everything in JS is an Object). The value of the this keyword is determined by how/where the function was executed. This means that if we are not careful we can lose the scope of what this is actually pointing to. Luckily, all JavaScript function object has access to some very special methods which we can use to explicitly state what this should reference. These methods are bind(), call(), & apply(). In this article we take a refreshing look at the bind(), call(), & apply() methods. Enjoy!
Creating JS objects that has no prototype

For Example: Date objects inherit from Date.prototypeArray objects inherit from Array.prototype What if you want to create an Object that does not have a prototype? Here's a neat little way to do it: const blankObject = Object.create(null) When creating objects using Object.create(),…

Let’s Create A URL Shortener
Chances are you've heard about or used URL shortening services like bitly, and tinyurl. These services allows you to enter long (and quite ugly) URLs and in turn gives you a very short (more appealing) link which you can use instead of the long URL. Shorter links takes up less space and are easier to share and type
JavaScript Objects – Basics
A JavaScript object is a variable which can contain many values. These values can be represented using name:value pairs (name and value separated by a colon). These named values are either referred to as properties or methods, depending on what's stored in them. OBJECT PROPERTIES Most objects contains at least one property. Properties describes the…
