It is a TypeError and its error message usually takes the following forms: console.time is not a function console.time(...) is not a function The first error message is usually caused by accidentally modifying the built-in console object or reassigning the console.time property to a value that is not a function. One of the main causes of the second error is the way JavaScript internally handles Automatic Semicolon Insertion (ASI). Continue reading to learn more about the…

Hi everyone, I'm Antonio, CEO at Litlyx. Today, I want to share a huge milestone with you. Over the years of my career as a Software Developer, I’ve gained so much from the Open-Source community. It’s likely that, in your codebase, you have 10 or more dependencies on open-source libraries in each tech stack you use. Thanks to this thriving community worldwide, we, as individuals, can grow our coding knowledge immensely. The past five months have been a rollercoaster of emotions for me. But now, it’s time to give back and pay the debt I've accumulated over the years from…

NPM peerDependencies in Depth: A Comprehensive Introduction

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, node, npm, software, webdev

As Javascript developers, we all know two different dependencies in our projects, dependencies and devDependencies, but what about peerDependencies? In this series, we will examine this less common dependency in Javascript. We will study what they are, what I need to know about as a library user, and what best practices are for library authors. What are dependencies in NPM Let's recap the different common types: dependencies: these are the tools used in your application; a good example is react, angular, and express. When your application is in production, the code of the libraries on dependencies will run under the…

stp2y0 CommentsNewsai, coding, community, development, engineering, inclusive, javascript, node, software, webdev

React Thunk and React Saga are middleware libraries for handling side effects in React applications, especially for managing asynchronous operations like API calls. Both are commonly used with Redux but serve slightly different purposes and approaches. React Thunk 1. Overview: React Thunk is a middleware that allows you to write action creators that return functions instead of action objects. This is useful for handling asynchronous operations like API requests or complex synchronous logic (like conditional dispatching of actions). The returned function receives dispatch and getState as arguments, allowing you to dispatch other actions or access the current state within the…

20 Essential JavaScript Concepts Every Node Developer Should Conquer

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, node, programming, software, webdev

Mastering Core JavaScript Concepts for Node.js Developers JavaScript has led the way in coding by being the language of choice for both frontend and backend development, with NodeJs at the forefront. Before the buzz around server-side JavaScript became cool, everyone recognized JS as the plucky maverick of the movement. While newer platforms such as Deno and Bun have started to provide competition, NodeJs remains the backbone of web apps and system software, with millions of lines of code written and executed using JS. Built on its unique single-threaded, asynchronous architecture and tools like Express, NodeJs is both a boon and…

1. Container A container is like a box that holds your application and everything it needs to run, such as libraries and settings. Containers are lightweight and can run anywhere without issues. Points to remember:- containers are isolated (independent of other containers). Portable: You can move containers from one computer to another easily. 2. Image An image is a template used to create containers. It includes the app code and everything needed to run it. Think Image like an Operating System in which multiple container can run. Points to remember:- Read-Only: Once created, you can't change an image. Layered: Images…
