Note: This article first appeared on the LogRocket blog Creating a strong password that you can actually remember isn’t easy. Users who use unique passwords for different websites (which is ideal) are more likely to forget their passwords. So, it’s crucial to add a feature that allows users to securely reset their password when they forget it. This article is about building a secure reset password feature with Node.js and Express.js. Now, let’s…

The guide to signal handling in Rust
A signal is a software interrupt sent to a process by the operating system or another process to notify it of an event. For example, when you try pressing Control+C while your program runs on a terminal, it terminates the process, correct? That’s one of the most common signals and signal handling you can see in action. We’ll explore how to handle that signal and others in Rust. A signal can be…

Higher-Order Functions in Javascript
Functions are a fundamental building block of JavaScript. They can be used to perform calculations, manipulate data, and control the flow of execution. In JavaScript, functions are also first-class citizens, which means that they can be treated like any other value. First-class citizen in a programming language means that an entity (such as a function) has the same properties and abilities as other entities. This means that functions can be:…

Rust’s Newtype Pattern: Adding Type Safety and Clarity
The newtype pattern is a Rust idiom that can be used to add type safety and clarity to code. At its core, the newtype pattern involves wrapping an existing Rust type (like a number or a string) inside a new struct. This might seem unnecessary at first, but the magic is that this new struct becomes a distinct type and ensures that you are using the correct type where necessary.…

Rust mem::swap Function for Value Swapping
In Rust programming language, memory efficiency, and safety is a feature. The mem::swap function, allows you to swap values between variables efficiently. Understanding mem::swap: In Rust, the std::mem module offers a collection of functions that deal with memory-related operations. Among them, the swap function stands out as a convenient way to exchange the values of two variables. The function is designed to work with mutable references to variables, allowing for…
