Having a brilliant company idea is not enough to attract customers and build a strong brand. The right technology stack is a crucial part of the development of new products. Therefore, the main factors determining what tech stack you should choose are time to market, scalability, security measures, and financial resources that are accessible. Technologies have a huge impact on cost estimation, team hiring, and the likelihood of third-party integrations.

\
Why is JavaScript so popular with startups? And what are the benefits and applications of the JavaScript stack? Read this article to find out.

# **Why do startups choose JavaScript?**

## Universal nature

JavaScript allows building almost anything, including desktop apps for Linux, Windows, and Mac computers as well as web and mobile applications. A chatbot, a social media app, or IoT system components can all be created using JS.

## Rich ecosystem

JavaScript has evolved from a browser language to a vast ecosystem of tools and extensions. Due to JavaScript's popularity, there are a number of resources and sample code online. It saves effort for developers and helps focus on the original software functions instead.

## Large community

According to [Stack Overflow's survey](https://survey.stackoverflow.co/2022/#overview), JavaScript was the most widespread programming language among developers worldwide in 2022. A vast JS programming community additionally makes it easier to find qualified specialists with the optimal price-quality ratio.

## Useful libraries

JavaScript's libraries, in general, are collections of pre-written code fragments that can be used and reused to carry out standard JavaScript operations. Libraries offer many standard functionalities so that developers don't have to worry about of common functions and may use JS libraries to quickly generate web pages with UI elements, language tools, math operations, and other things. This accelerates development and reduces error-prone areas.

\
These are the three most popular JavaScript libraries available today.

# JavaScript stacks for startups

The most popular JavaScript stacks are **MEAN** and **MERN** stacks.

## MEAN Stack

MEAN is a comprehensive set of JS frameworks and technologies that speed up app development and integrate flawlessly. It is named after four key technologies that make up the layers of the stack.

\
**M**ongoDB — document database
**E**xpress.js — Node.js web framework
**A**ngular.js — a client-side JavaScript framework
**N**ode.js — the premier JavaScript web server

\
MEAN applications can be used in many ways with a cross-platform write-once approach. You may easily create a mobile version of your online application using the same technology. The ready-to-use Node.js modules greatly accelerate engineering and drastically reduce development costs. The integration between the components of the stack is logical and simple because all the components are based on JavaScript and JSON.

\
It is a good option for creating cloud native applications because of its scalability and capacity for handling multiple concurrent users. The AngularJS frontend framework also makes it ideal for developing single-page applications (SPAs), calendars, expense tracking, interactive forums, workflow management tools, news aggregation sites and many more.

## MERN stack

MERN is very similar to MEAN with one exception — Angular is exchanged with React, whose popularity has steadily grown over the last few years.

\
**M**ongoDB — document database
**E**xpress.js — Node.js web framework
**R**eact.js — a client-side JavaScript framework
**N**ode.js — the premier JavaScript web server

\
ReactJS’s component-based approach has reusability of codes, making app development faster and easier.a fantastic framework for running the same code on the browser and the server. MERN stack comes with a pre-built set of testing tools for app development. The Model View Controller architecture is also supported by this stack, making the development process easy and seamless.

\
MERN stack is ideally suited for cases that are JSON-heavy, cloud-native, and that have dynamic web interfaces. Examples include workflow management, news aggregation, to-do apps and calendars, and interactive forums/social products.

# Conclusion

Consider numerous factors while selecting a set of technologies for your product, including a business domain, technical requirements, target audience, possible integrations, resources, etc.

\
Thanks to an impressive number of JavaScript frameworks for startups, its libraries, and third-party APIs integrations, JavaScript is considered one of the most useful technologies for startups.
