For transforming your product idea into an actual end product, you first have to choose a Technology Stack. Also, make sure that it is affordable, and accessible enough. Startups in recent times have been using JavaScript (JS), to begin, their initiatives. But, Why JavaScript? Because it can be applied in almost every place- in any industry and area. Also, more developers mean a lower rate, and, obviously, costs are important for startups. But if we take a more profound look, we’ll find a few more reasons from the development mindset. In this blog, we shall cover some aspects of why Startups use JavaScript.

Here is a brief outline of the Technology,


JavaScript is a language designed to meet the requirements of the extending landscape of the internet. Since its inception, it has risen in popularity and usefulness and is now present in more than just web development. It is a vital technology element of interactive web development, and hence, it is utilized more often in this industry.


JS is useful for building different kinds of software such as games, computer programs, web apps, and even technologies like blockchain. It is arguably one of the most famous programming languages for the web.

Now, let’s see why startups use it.

Reasons Why Startups Use JavaScript

✸ Development Speed is good


Some codes are very long. Regardless, by choosing JavaScript technology for a startup you can lower the number of lines drastically.

The speed of JS development services is demonstrated not only by its performance and clarity but also by its multiple frameworks and libraries. By keeping modules useful and lines of code clear, you can save lots of time while developing. JavaScript for a startup also allows you to use identical technology for both the front and back end, which implies speedier communication.


✸ Interoperability on diverse projects


Reusable experience helps to move faster. When using JS, the same developer not only saves time but also ensures the consistency of the product on different platforms such as websites and progressive web applications, native-like apps on iOS, Android, Windows, macOS, and Linux. In addition, it also helps with solutions for IoT devices and works on different clouds and server-side infrastructures.


Whether you are making a REST API or AWS microservices architecture, or just an app executing on all widespread devices, you are free to use the same modules, package manager, task runner, IDE, libraries, and all other things. There is no requirement to solve the same tasks for diverse platforms. Once you write the code it is reusable.


✸ Third-Party APIs


With the help of third-party APIs, you can easily use advertising iframes, video embeds, helper libraries, or specific social media functionality, for instance, tweets from Twitter or comments from Facebook right within your web app. Node.js, in particular, allows integration of almost any solution your project may need. In many cases, an opportunity to apply third-party integrations is viewed as one of the main benefits of using JavaScript for startups.


✸ Technology Stack 


Generally, the JavaScript technology stack for startups comes as MERN or MEAN stack. The common technologies in both the stack remain pretty much the same – MongoDB, Express.js, and Node.js, the sole difference is Angular and React. Angular for MEAN and React for MERN.


Webbybutter has an excellent team of MEAN and MERN Stack  Developers. You can get a detailed plan of our development approach and Kickstart your startup.

When to choose MERN Stack for a Startup?

  • If you have less time to begin the business, then choosing MERN Stack is a more feasible option. This guarantees speedy web and app development.
  • Less time is needed to train the developers for the MERN stack.
  • MERN is cost-effective and you can establish your online presence under your budget.
  • Developers build an app or website even faster and more effectively using many flexible tools.
  • If your business idea is big, going for the MERN stack would be beneficial.
  • MERN stack delivers a more scalable and robust development environment.
  • MERN stack is a good option for developing mobile apps.

When to opt for MEAN Stack for a Startup?

  • MEAN stack delivers a website or full-stack app only using JavaScript language.
  • It offers high speed, maintenance, reusability, and testability to your startup app.
  • Cost is for developing low as the technologies are open source in the MEAN stack development cost is lower in it.
  • The code of the MEAN stack is easily moved to another framework and is called Isomorphic coding.
  • MEAN stack developers can code less and still get desired results.
  • Has in-built testing tools which save time.
  • MEAN stack enables easy to switch between server-side to client-side.
  • Using Angular you can develop Single Page Applications easily and boost your startup.


These were some aspects of why use JavaScript for your Startup. Here are some domains where JS can help you with your Startups,

  • Mobile App Development
  • Web Development
  • Games
  • Web Servers
  • Server Apps and so on…

Let’s see some well-known companies that are using JavaScript.

Top companies using JavaScript

✸ Uber


Uber is one of the biggest innovative taxi companies and its app needs to process a huge amount of data immediately and battle asynchrony, still it is known for rather clean code and originally low implementation costs.


The secret behind such success is somewhat hidden in its technology based on JavaScript. Using the same language on both front and back-end sides lets the creation of a responsive isomorphic application for Uber both drivers and riders. Also, using Node.js, developers of the Uber app managed to build an event-driven environment where more than a million calls per second are processed correctly.

✸ Netflix


The streaming giant used Java for the server side and JavaScript for the front end. The back end was managed by a single large application executing Groovy scripts. This forced developers to work in 2 different programming languages. Node.js tackled this problem. So, when the company decided to redesign its online streaming platform in 2014, the development team shifted to Node.js. During that period, the JS library had already made a reputation as a simple framework with a variety of use-case.


By utilizing the same JavaScript framework on the front-end and back-end, developers lessened their workload and increased the quality of the final web app. By using separate APIs written in Node.js, Netflix was able to consolidate its total development time and enhance its application’s speed.


✸ LinkedIn


After switching from Ruby on Rails to Node.js the app demonstrated adequate performance and memory use. In certain systems, it functioned 25 times quicker.


The front-end and back-end web development began to operate in the same language, which implied clear communication, quick implementation, and cost reduction could now be executed by a single group. Also, the number of servers dropped significantly.


✸ Candy Crush


King Digital Entertainment developed the popular game Candy Crush Saga with the JavaScript programming language. Using the flexible nature of this framework, developers gave it a look and sense like the Facebook web app.


Further, Candy Crush also Leveraged Facebook’s React Native JS framework to link the mobile game with Facebook’s web application. This authorized users to invite their friends to the game and compare their scores against their social network. This feature itself made the game so popular and kept users engaged beyond their initial download.


The Candy Crush model has revamped the mobile gaming industry. Apps like Bejeweled and Zookeeper Battle have used JavaScript to make similar successful games. Many games even replicated the gaming concept from Candy Crush. This indicates that JS will continue to dominate the mobile gaming market because of its comprehensive frameworks and wide range of use cases.


The list of such applications goes on but you can see how JS technology can help your startup in many ways.

Final Take 

JavaScript is not going anywhere and with increasing demand for mobile apps, it’s only going to get better. The utility is there and we also witnessed some interesting cases where JS is used but still, if you are looking to use the technology then you must consider your requirements and assess the Niche for your startup. This will help you get an estimate of which Technology Stack will suit you the best.
