The quirky little toy language was capable enough to create professionals who acted like some kind of driving force of the internet. As more and more browsers were introduced, CSS and HTML came along in order to create cross-browser incompatibilities. By doing this they would clearly define the need for front-end engineers. As a result, today, front-end specialists are considered as one of the most sought-after candidates across the globe.
Significance of a Front-End Engineer
In the above image, the UI layer on the browser was the sole domain of the front-end engineers whereas the back-end UI layer was something where front-end and back-end engineers met and then the rest of the server architecture was where the guts of the application lived. This is the point where one finds data processing, caching, authentication, and all other pieces of functionality that were critical to the application. So the front-end was the browser and everything else was the back-end.
Introduction to Node.js
In a nutshell
I simply love the platform and all the possibilities offered by it. Using Node.js for the back-end UI layer also frees up the back-end engineers from worrying about a whole host of problems in which they have no concerns or vested interest.
