What distinguishes MEAN Stack Development from other types of development?

The following are the main characteristics of MEAN Stack Development:

Speedy and straightforward

The development of apps/websites that run on a single language, such as JavaScript, is considerably easier and faster.

Active Dev Community

MEAN Stack is based on JavaScript, the most widely used programming language on the planet. As a result, it comes with one of the most active development communities, making finding solutions easier and more accessible to all parties.

MEAN Stack Flexibility

MEAN Stack is incredibly suitable for a wide range of online applications due to the total adaptability of its programming language, i.e. JavaScript.

What are the advantages of developing a MEAN stack?

MEAN uses a single language

Because MEAN Stack is built on JavaScript, every technology within it is also based on JavaScript. This simplifies application development because JavaScript is used to control everything from database configuration to frontend and server-side processing. As a result, you won’t have to hunt for other developers who are experts in a specific language or server.

MEAN is Open Source and Cost-effective

Every technology in MEAN Stack is written in JavaScript, an open-source programming language. As a result, the platform is open-source as well. You don’t have to pay anything to download and use it. As a result, MEAN Stack development firms do not charge you licence fees.

Furthermore, when compared to the LAMP Stack, MEAN requires less developers; for example, with LAMP, you’ll need engineers who know JavaScript, PHP, and MySQL.

MEAN is highly flexible

After the programme has been developed, the developer can easily test it on the cloud. MEAN is extremely versatile since it allows you to a. build, b. test, and c. deliver an app without any issues. Furthermore, once you’ve added a field to the form, MEAN allows you to add additional data.

MEAN is isomorphic

MEAN makes isomorphic coding simple. Developers may quickly move their prepared code from one framework to another using MEAN. Isomorphic codes are those that were written in one framework but can be reused in others. Furthermore, this code functions flawlessly as if it were written natively. One of the most significant advantages of MEAN Stack app development is this.

MEAN is user-friendly and provides excellent UI

In any web/mobile app, Angular is well-known for its amazing user-interface (UI) and user experience (UX). As a result, many of your favourite brands employ Angular.JS, which is widely regarded as the best front-end technology. It also supports the MVC (Model-View-Controller) architecture, which ensures that the user interfaces are of high quality.

MEAN is re-usable and speedy

MEAN uses Node.JS, which results in great speed and reusability due to Node.non-blocking JS’s architecture. Angular.JS is also an open-source JavaScript framework, which means it’s reusable, testable, and easy to maintain.

MEAN is well-suited to the cloud

MEAN Stack’s development approach makes use of public repositories and libraries, lowering the overall development cost. MongoDB also makes advantage of cloud functionality in the app, which reduces the amount of disc space required.

MEAN makes it easier for developers

JavaScript has become the most common scripting language among next-generation developers in the last five years. JavaScript can be used in a variety of places, including servers, games, blogs, operating systems, and even robots. Not only that, but JavaScript is one of the most commonly used languages on GitHub.

With JavaScript’s and prominence in the realms of web and mobile app growth, it’s more important than ever for JavaScript developers to stay up to date on the best performance practices. That’s why we’ve compiled a list of the top 15 JavaScript tips that will boost your productivity by leaps and bounds.

Define variables locally

When you call a function, the variables used to describe it are stored within. Variables are divided into two categories.

Local variable: – Variables that are defined only within themselves.

Global variable: – Variables that are only described within themselves are referred to as local variables.

Variables that are used in the script are referred to as global variables.When you call a function, the browser performs a task known as scope lookup. When the number of scopes in the scope chain grows, so does the amount of time it takes to access variables that aren’t part of the current scope.

This is why it takes a longer time for an engine to access a global variable than it does a local variable. This means that if you identify the majority of variables locally, the time it takes the engine to check for them would be significantly reduced. As a result, the application’s average pace will improve.

Keep codes light and small

It’s important to keep mobile app code as light and lightweight as possible in order to retain high performance. Keeping the code light and small will help to minimise latency and increase speed.

You should ask yourself the following questions when you’re in the creation stage.

Another way to improve the application’s output is by shrinking and diminishing multiple JS files into one. If your app has seven JavaScript files, for example, the browser will need to send seven different HTTP requests to get them all. To avoid this, simply combine the seven files into a single streamlined file.

Event Delegation implementation

Event delegation allows you to use a single event controller, which aids in the efficient handling of a specific form of event across the entire page. Due to the presence of multiple event handlers, large web applications can stop if Event Delegation is not used. Event delegation has a number of advantages, including less functionality to handle, less memory to store, and less connections between DBAs.

Avoid unwanted loops

Looping in JavaScript is not recommended because it puts additional pressure on the browser. It’s important to remember that in the loop, you do less work. The less effort you put into the loop, the sooner it can complete it. There are also some common tricks, such as storing the length of an array in a separate variable rather than reading it at each loop iteration. This could go a long way to optimize your code and run things in a more efficient manner.

Gzip compression

Gzip is a compression and decompression software application that is used by most clients and servers. When a browser that supports gzip makes a request for a resource, the server compresses the answer before sending it to the browser. Gzip compresses large JavaScript files and saves bandwidth, which eliminates latency and time lag and improves the overall performance of the programme.

Minimize DOM access

The interaction of the host browser with artefacts (DOM) outside of the JavaScript native environment causes severe performance lag and unpredictability. This occurs because the browser must refresh each time. To prevent this, simply reduce the amount of DOM access. There are a few options for accomplishing this. For example, you can store references to the browser objects or you can decrease the overall DOM traversal trips.

Boost performance by caching object

This can be accomplished in two ways. The HTTP protocol cache is the first choice. The second choice is to use the JavaScript Cache API, which can be accomplished with the help of a service worker. Scripts are commonly used to access specific items. By using a variable in references to that object or simply storing the repeated access object within the user-defined variable, you can achieve substantial performance gains.

Get rid of unused JavaScript

This approach is well-known for speeding up the browser’s code compilation. The transmission time is also reduced as a result of this. To get rid of unused JavaScript, you’ll need to think about a few things, such as finding functionality that isn’t being used by anyone. The website can load faster and have a better user experience as a result of this.

Refrain from using too much memory

One of the most important skills a javascript developer must have is the ability to keep memory use to a minimum. It’s because determining the memory requirements of the system when it’s used to run your app is difficult. If the code demands a new memory reserve for the browser at any point in time, the browser’s garbage collector will be invoked, and JavaScript will be terminated. If this occurs on a regular basis, the page will slow down.

Implement the various optimizations

You must always use the algorithms with the least computational complexity to solve all tasks with optimal data structures.
