Lately, as I have been focused on Node.js development, I have spent time learning about the underlying ideas that power the platform. Node.js departs from more traditional methods of handling I/O operations via the usage of threads, accomplishing efficiency and speed with its non-blocking I/O design. This non-blocking design is…

When we think of programming paradigms, the one that receives the most coverage is Object-Oriented Programming. This is to say, a programming paradigm is how code is implemented and executed, and in the case of OOP, it is via the use of classes and objects. However, aside from the OOP…

In JavaScript, anything that is not a primitive value such as strings or integers is an object. What this means is that functions are actually objects or at least specialized objects. This also means that functions have access to properties and methods like all other objects do. …

To recap my last blog, “Exploring Closures with JavaScript Functions”, to understand closures, it’s essential to remember that functions create an enclosed environment known as a namespace. Namespaces allow you to work with variables that have been defined within other namespaces or scopes without overwriting them. …

Continuing with the theme of functions and their many lesser-known features, closures are one of the more important and powerful features to be aware of. In understanding them, we first have to start with the idea of a namespace, which is a space where variables bindings are made. …

In programming, functions are foundational. They modularized logic which creates reusability and cleaner code. Sometimes, functions are able to carry out their logic with outside input known as arguments. Arguments are then used within a function’s body to compute a return value. Functions are able to utilize arguments through function…

In JavaScript, functions are objects which provide a modular way to define a set of procedures or operations that can be used many times within a program. By using functions, code is abstracted away reducing potential repetitive logic and helping to maintain legibility. But when working with functions, it is…

Working with data can take two forms, either some work is done directly to it resulting in the data being fundamentally changed or it can be copied, and then have some work done to the copy. Most, if not all of the time, working with data in an immutable way…

Usually when we think of a data structure being iterable, we think of arrays and strings. JavaScript provides many ways to iterate over an array or string, ranging from the standard for-loop to more modern variation like the ES6 for/of loop. However, because objects are not inheritently iterable, JavaScript has…
