Internal Representation Of Objects In Java Script Objects, in JavaScript, is it’s most important data-type and forms the building blocks for modern JavaScript. These objects are quite different from JavaScript’s primitive data-types(Number, String, Boolean, null, undefined and symbol) in the sense that while these primitive data-types all store a single value each (depending on their types). Objects are more complex and each object may contain any combination of these primitive data-types as well as reference data-types. An object, is a reference data type. Variables that are assigned a reference value are given a reference or a pointer to that value. That reference or pointer points to the location in memory where the object is stored. The variables don’t actually store the value. Loosely speaking, objects in JavaScript may be defined as an unordered collection of related data, of primitive or reference types, in the form of “key: value” pairs. These ...

HTTP/1.1 Vs HTTP/2 A Brief History Of HTTP If we’re going to talk about the transition from HTTP/1.1 to HTTP/2, it’s worth taking a quick trip back to the flannel-soaked 1990s. Back then, HTTP was a simple protocol for a simple job – transporting documents from a web server to your computer as efficiently as possible. This is because the web was simple, made up of documents and a spattering of images that were no sweat for the hardware of the time to sling around. HTTP, which stands for Hypertext Transfer Protocol , saw wide adoption in the early 1990s to facilitate this, transferring “hypertext” documents. These were simple documents comprising mostly text and a few images, marked up with HTML to add formatting and links to other hypertext documents. By 1996, the 1.0 specification was adopted. This version was elegant and simple for the needs of the mid-90s web – make a connection, download a file, close the connection, and repeat for each file needed to display a w...
