Since JavaScript’s inception in 1995, it primarily functioned as a client-side (front-end) programming language. In its early days, it additionally gained a repute for having poor efficiency capabilities. Nonetheless, since then, a big period of time, cash, and power has been invested in enhancing the language.
This funding led to the event of many standard libraries and frameworks utilizing the language. Some notable examples embody jQuery, React, AngularJS, Vue, and Node.js.
What Is Full Stack JavaScript?
Full stack JavaScript is the observe of utilizing JavaScript on each the back and front finish of an utility. JavaScript is broadly recognized for its front-end libraries and frameworks, however on the back-end, it now has Node.js.
Though Node.js wasn’t the primary try at using JavaScript on the server aspect of software program growth, it definitely was essentially the most profitable try. Right this moment, server-side JavaScript is synonymous with Node.js, and JavaScript is formally a full-stack programming language with three extremely popular stacks.
The MERN Stack
JavaScript’s MERN stack is arguably the preferred stack, consisting of 4 main applied sciences. On the entrance finish of those purposes, you’ve the React library, a well-liked JavaScript library developed by Fb. This library owes most of its recognition to a number of various factors, together with its flexibility, efficiency optimization, and its speedy adoption by main tech corporations.
The opposite three applied sciences on this stack are Node.js, Specific, and MongoDB. These applied sciences work collectively on the backend of the MERN stack.
Node.js (also called NodeJS) is greater than only a framework. It’s an asynchronous JavaScript runtime setting that operates on an utility’s server aspect to handle particular processes. The builders of Node.js place emphasis on the software program’s non-blocking I/O operations. This characteristic offers Node.js a bonus above a few of its opponents, by permitting you to develop purposes with out the priority of deadlocks.
One other necessary characteristic of Node.js is that it’s event-driven. Because of this it makes use of an occasion loop as a runtime assemble, somewhat than as a library. This occasion loop is answerable for Node.js’ means to carry out non-blocking I/O operations.
Specific (also called Specific.js) is a Node.js framework that allows Node.js to perform particular duties. For instance, Specific performs an instrumental function in how Node.js handles the routing of an utility, by simplifying the method. In most Node.js purposes, Specific handles all of the HTTP requests.
MongoDB is a NoSQL database administration system. Like Node.js, MongoDB is a trailblazer in its area. For the longest time, MongoDB has been synonymous with NoSQL databases. Builders love utilizing MongoDB as a result of it’s straightforward to make use of and fewer inflexible than its SQL counterparts.
The MEAN Stack
What distinguishes the MEAN stack from the MERN stack is the know-how on the entrance finish, which is Angular. Angular has a sophisticated historical past. The primary model of Angular (AngularJS) was constructed solely with JavaScript. Nonetheless, the Angular that you already know at this time is a TypeScript (which is a superset of JavaScript) internet growth platform.
Angular is a component-based framework that gives built-in assist for important internet growth mechanisms, corresponding to routing. Moreover, Angular serves as a growth platform, providing superior options that you’d sometimes must supply from exterior libraries or frameworks. One such superior characteristic is Angular’s internationalization instrument.
The internationalization instrument facilitates localization by extracting tagged textual content for translation into totally different languages. This instrument helps a number of translations and even lets you format information based mostly on the placement of the appliance’s consumer. On the again finish of the MEAN stack, you’ve Node.js, Specific, and MongoDB.
The MEVN Stack
Although the MEVN stack is arguably the least standard among the many three main JavaScript stacks, it nonetheless maintains a robust neighborhood. The MEVN stack consists of Node.js, Specific, MongoDB, and Vue.
Vue (also called Vue.js) is a JavaScript framework. Much like React and Angular, Vue makes use of a component-based mannequin that lets you develop each easy and sophisticated consumer interfaces to your purposes. This framework boasts two core options, it gives declarative rendering and reactivity.
The Vue framework achieves declarative rendering by permitting you to explain a UI’s output via a JavaScript state. JavaScript state additionally performs an necessary function on this know-how’s means to be reactive, because it permits it to replace the Doc Object Mannequin (DOM) when adjustments happen.
MERN vs. MEAN vs. MEVN
The comparability among the many three main JavaScript stacks basically comes all the way down to the three applied sciences on the entrance finish. Subsequently, the desk beneath evaluates the stacks utilizing React, Angular, and Vue.

Studying Curve |
React has a easy studying curve. |
Angular has a steep studying curve, on account of its in depth record of options and its utilization of TypeScript. |
Vue is taken into account extra beginner-friendly in comparison with React as a result of it makes use of a template syntax intently resembling HTML, whereas React makes use of JavaScript XML (JSX). |

Flexibility |
React may be very versatile when it comes to venture structuring and element reusability. |
Angular is opinionated about venture construction on account of its many built-in options and conventions. |
Vue falls someplace between React and Angular. It gives a excessive degree of flexibility whereas additionally providing its personal set of conventions when wanted. |
|
Safety |
React doesn’t present any built-in security measures. |
Angular has a built-in safety characteristic that helps to stop cross-site scripting (XSS) assaults. |
Vue additionally has a built-in safety characteristic that helps to stop XSS assaults. |
|
Rendering Efficiency |
React makes use of a Digital DOM (VDOM), which is a replica of the particular DOM. When the appliance’s state adjustments, React creates a digital illustration within the VDOM, which later updates the precise DOM in a course of referred to as reconciliation. This strategy minimizes the quantity of precise DOM manipulation (which is an costly operation). |
Angular makes use of a change detection mechanism that screens the appliance state and updates the DOM when it detects adjustments. |
Vue makes use of React’s Digital DOM and combines it with its personal reactivity system. This basically gives Vue with the most effective of each worlds in the case of rendering. |
|
Accessibility |
React doesn’t assist accessibility. |
Angular has a number of instruments and options that assist accessibility. |
Vue doesn’t assist accessibility. |
Benefits of Full Stack JavaScript
An apparent benefit of full-stack JavaScript is that it reduces the educational curve for builders who select to make use of it for full-stack growth. It is usually inherently asynchronous, enabling you to develop extra scalable purposes. Efficiency-wise, JavaScript runtime (significantly Node.js) is among the many greatest, offering spectacular server-side processing.
Nonetheless, there’s a notable drawback to having full-stack JavaScript. Whereas server-side JavaScript excels in each I/O-bound and event-driven processes, it’s nonetheless not the perfect selection for CPU-intensive duties, particularly when extra highly effective languages like Python and Java can be found.
