Node.js’s disadvantages include the following: 

1. Performance bottlenecks

When utilizing Node.js, you may encounter several downsides, such as the inability to effectively handle CPU-intensive operations. To comprehend the fundamental cause of the issue, it’s necessary to have some context for the scenario.

Everyone is aware that we utilize Node.js as a runtime environment for server-side JavaScript execution. JavaScript is a front-end programming language that enables you to swiftly perform a job using a single thread. It will not need threading since all JavaScript jobs are lightweight and use minimal CPU, which might result in bottlenecks if there are several tasks to manage.

When it comes to Node.js, the primary issue arises when it gets a CPU-intensive job. Once it receives a hefty job, it will dedicate all available CPU to processing it first, before responding to the other queued requests. As a consequence of the sluggish processing and delay in the event loop process, Node.js is inadequate for handling large amounts of computing.

2. Immature Tools

However, although Node.js has mature modules, there are additional tools accessible in the npm registry that are of low quality and are not tested. It lacks a systematic registry for distributing tools depending on their ranking and quality. This creates a difficult condition for determining the optimal answer for your needs without first comprehending the requirement for it.

The Node.js ecosystem is open-source, and Joyent oversees its quality. Nonetheless, it is possible that the remaining tools do not adhere to the worldwide organization’s quality criteria.

Conclusion

Node.js has gained widespread popularity as a result of its many advantages for developing web-based and interactive websites. However, it comes in several versions, and while you may select any, it is generally recommended to use the most recent version to benefit from improved features and capabilities. You may go to the preceding article to learn how to install and verify the Node.js version that is currently installed.
