Next-Gen Technology For The World Wide Web
ECMAScript-6 involves a lot of cool features like const & let keywords and arrow functions which the developers have been asking for years.
This journey includes and is not limited to –
- What can you do with JS?
- Where does JS code run?
- Top 6 newsletters for developers
On Christmas Day – 1990, the world saw its first web browser, developed by Sir Timothy Berners Lee on a NEXT computer system and was called – WorldWideWeb
This internet browser was renamed Nexus to eliminate the confusion with the World Wide Web .
Nexus was developed for NeXTSTEP Operating System. And if that weren’t enough, this guy also set up the first Web server around the same time.
Now, if I ask you what the internet is?
You’ll probably start with it; it’s a computer billboard, but it’s a line, several universities, and everything is joined together, right? And others can access it, right?
Well! Kind of, Yes! But No! And please wait!
That’s not what you think it is.
For the foreseeable future, our story starts in December of 1991 when Al Gore (yes, the environmentalist) invented the internet during a session in the United States Congress. He took the initiative in creating the internet.
All he did – was introduce the Gore bill, which provided funding for the first mainstream web browser, Mosaic. It was developed by Marc Andreessen and Eric Bina at the University of Illinois and released for UNIX systems in January 1930. Later that year, there would be ports for Macintosh and Windows, and mosaic was the first web browser to start bringing the Internet to the mainstream.
After Andreessen graduated, he moved to California to co-found Netscape, and within just a couple of years, the Netscape Navigator controlled around 80% of the browser market share.
And Around this period, Andreessen realized that browsers needed to become more dynamic. And web designers needed some glue language to make their websites more interactive.
So, naturally, the first thing to turn to is the super-trendy ‘Java’ programming language from Sun Microsystems”.
But they quickly decided that the idea sucked, so Plan B was to recruit a guy named Brendan Eich (a prominent American Software Programmer). Eich’s job was to put the scheme programming language in the browser but maintain a syntax that still resembled Java, and he needed to have that done quickly.
Writing a perfect programming language in ten days is impossible; Brendan Eich knew this very well. So what he didn’t do was write a highly specialized language designed only for browsers of the 90s. Instead, he wrote a flexible multi-paradigm language that developers could use to apply their language patterns too!
By September 1995, “Mocha” was renamed live-script. It was shipped in the first beta releases of Netscape Navigator 2.0.
From day one, mostly with annoying pop-up windows, a company was becoming very popular around this time, and they were launching their browser called Internet Explorer (it’s gone now!!).
Another major thing going on in recent times, i.e., in 2015, was the rise of React.js. It took some of the concepts of Angular.js with declarative UI but improved them with unidirectional-data flow-immutability and the use of virtual DOM. And React has been the framework that has solidified modern-day declarative UI patterns.
With TypeScript, the developers can use object-oriented programming, strong datatype casting, and, more importantly, very scalable.
What can you do with JS?
These days, you can build a full-blown web or mobile apps and real-time networking applications like chats and video streaming services, command-line tools, or even games.
Here’s an example –
Where does JS code run?
So, in a nutshell, you can run a JS code inside a browser or in node browsers. Node provides a runtime environment for your JS code.
Well! The ECMAScript is just a specification, and JS is a programming language that conforms to this specification. So we have this organization called ECMA , which is responsible for defining standards. They take care of this ECMAScript specification.
The first version of ECMAScript was released in 1997. Then starting in 2015, ECMA has been working on annual releases of the newest specification.
- JS follows mostly all structured programming syntax with all loops and conditions like in C
- While it originally just had functional scoping with ‘var’, ES6 introduced the keywords ‘let’ & ‘const,’ which gave JS the much-needed block scoping.
- JS is a weakly typed & dynamically typed language and has sometimes received a lot of flak for its weakly typed nature.
- With asynchronous being the new challenge of all programming languages, JS evolved with its ‘Promises’ and ‘async/await’ in this field. With the introduction of observables through rxJS, Js has a robust asynchronous behavior.
- Its arrow functions are the best-loved feature of JS that the developers have been asking for for a long. It gives flexibility with ‘this’ and a ton of regular clean coding.
Hence, the game is not over; it has just begun.
Some JS frameworks like Angular, React & Express are among the top used and most popular going around just because of the simplicity of their usage, scalability, implementation ease, and tremendous community support.
Its Node.js , an open-source runtime environment to compile JS code outside the browser, has vast open-source community support and over 350,000 registered packages in npm (Node Package Manager), the most prominent package registry globally.
If we dive more deeply into the intricacies of JS, we will see that it is like any other programming language that you learned at your school but with a lot more flair and ease in coming along.
So, here are the top 5 JS frameworks that you should consider now and for times ahead –
- React — Skyrocketing like never before!
- Vue.js — Making noise with around 174K unforgettable GitHub Stars!
- AngularJS — The whole Front-end development framework to create single-page web apps.
- Ember.js — Consider it if you want to boost your development team’s productivity.
- Svelte — Big things in the small packet!
Now, I’m heading to wrap things up!
With the popular fan base among developers and fantastic community support, JS is a preferred language for any freshman looking to get a job and enter the software industry.
It may be toil, in the beginning, to choose between the ton of frameworks on which ones to use & learn, but once the priorities get sorted out, JS is an honest & long-time friend.
Below are a few free websites that you can use to learn, practice, and master JS –
