Advantages of Using Node.js and Its Technical Questions

As you evaluate the pros and cons of Node.js for your next project, of course, it’s important to understand just how powerful this run-time environment can be. Stay with us here the list of node js technical interview questions are long, but an important part of understanding your development plan.

The Ability to Scale Up Quickly

Each of the nodes in Node.js is based around an “event.” A customer buys an in-app purchase, or sends an email to customer service, for instance. The amount of nodes you can add to your core programming function are nearly limitless. This means you can scale vertically, adding new capability paths that lead back to your core application code. Or, you can scale horizontally, adding new resources to existing programming.

Speed and Performance

Its non-blocking, input-output operations make the environment one of the speediest options available. Code runs quickly, and that enhances the entire run-time environment. This is largely due to its sectioned-off system. But it also has to do with the fact that it runs on Google’s V8 JavaScript engine. Its apps are more likely to be programmed end-to-end in Javascript, and that plug and play interoperability contributes to speed and performance.

Flexibility

In a discussion of Node.js pros and cons programming flexibility is perhaps the biggest benefit of all. When you make a change in Node.js, only that node is affected. Where other run time environments or frameworks may require you to make changes all the way back to the core programming, it doesn’t require anything more than a change to the node.

Efficient Caching

In a debate over the pros and cons of Node.js, caching always comes up as a key Node.js benefit. It has a powerful ability to cache data. When requests are made to the app, they are cached in-app memory. Consequently, when requests cycle through execution and re-execution, the nodes are still able to run efficiently and not be bogged down by historical data.

Fast to Market Development

Node’s basis in JavaScript brings many benefits to the table, especially the ease at which developers can add more features and predesigned tools and templates. In fact, it has an extensive package management library, with thousands of open-source options that can be added to your app project immediately. These pre-packaged options not only reduce your time to market, but they reduce your programming budget, as well. When evaluating Node’s pros and cons, this is a bottom-line benefit that can’t be ignored.
