In the ever-evolving landscape of JavaScript and Nodejs, developers are constantly discovering new ways to write cleaner and more efficient code. One such innovation is the ability to use top-level await() without the need for an enclosing async() function. This feature, introduced in modern versions of Nodejs (14.8.0 and later), provides an elegant approach to handling asynchronous operations in your codebase. In this blog post, we’ll delve into the mechanics of top-level await() and explore its benefits and use cases.
Nodejs provides a powerful filesystem API through the fs module, but the underlying filesystem behavior can vary significantly across different operating systems and filesystem types. This guide presents a comprehensive approach to handling these variations while maintaining robust and portable code. Understanding how Nodejs handles filesystem operations asynchronously through its event loop is crucial for writing efficient code.
In the world of data handling and transfer, one common challenge that arises is backpressure. If you’ve ever encountered a situation where data starts to accumulate like a clog while being transferred, you might have experienced backpressure. In this blog post, we’ll explore what backpressure is, how it affects data handling in Node.js, and how streams offer an optimized solution to deal with this issue effectively.
The word finally in Javascript is used in two contexts mainly; finally method with Promises and finally {} block with try-catch.
People intermittently use the finally keyword for both the context and have the assumption that they behave the same. However, there is slight difference in behaviour. The purpose of finally in both the context, however, remains the same.
Template literals are literals delimited with backtick (`) characters, allowing for multi-line strings, string interpolation with embedded expressions, and special constructs called tagged templates.
JavaScript template literals, introduced in ES6, are a powerful feature for string manipulation. They are delimited with backtick (`) characters and provide three main capabilities:
