The code is difficult to manage

[sohanuzzaman57]

Node js developers have an asynchronous programming model that complicates code management. This technology answers many callbacks because of its asynchronous approach. This function operates after each line of tasks, keeping several lines of tasks in the background that are still working. These callbacks will later cause callback hell which directly impacts the performance and quality of the code itself. This limitation makes understanding and managing code in Node js more troublesome.

5. High demand
Node js is in high demand and much faster than expected. This is why there are not many experienced Node js developers who fit the market needs. There is a common misconception that JavaScript developers are technically also Node js developers. In fact, you must understand the JavaScript backend first to be able to learn node js.

Even though the demand for Node js developers is list of italy cell phone numbers increasing, it is very difficult to find experienced Node js developers. So if you need the services of someone who is an expert in Node js, you will probably need a special team like SoftwareSeni .

Uses of Node JS
After explaining the various advantages and disadvantages of Node js above, now you certainly understand why Node js developers are in high demand.

To better understand the function of Node js and why the demand for this type of developer continues to increase, see the following uses of Node js.

1. Real time application
As discussed earlier, Node js can provide fast speed and performance. One of the uses of Node js is for real-time messaging , or chatting . The Node js environment can support intense traffic on a series of short messages when messages are displayed simultaneously by multiple users.

2. Collaborative tools
Its ability to process streams in real time allows for collaborative applications to be created. One example is Trello, a fairly popular project management application that uses the Node js platform which is great for developing applications that require immediate updates.

3. Data streaming applications
Node js is also capable of sending large amounts of data in several small packets and not sending them in one large single packet. This capability is very important for applications that provide audio or video streaming services . This platform is very suitable for streaming service tasks with modules that support data streaming and allow for the creation of readable and writable data streams. Even large streaming services like Netflix also use node js, so you can imagine how powerful the environment of this platform is.

4. Applications that depend on scalability
The strong scalability supported by Node js is the reason why this platform is used by applications that must have the ability to withstand peak load during peak hours. This is also the reason why Uber has Node js to develop its application.

Global taxi networks like Uber are always expanding their presence in the community. At the same time, taxi services like this are always in very high demand during holidays or during peak hours. Node js is able to handle these challenges very well.
